Reluctant to evolve my first Tyranitar....

It took a few tries but I got B/SE. It's kind of like DB/DC for Dragonite. Bite has the same damage and speed as DB did. You can fly all around and easily dodge anything with practice (and good reception). B/C does HUGE damage and you still have bite to dodge with. The only drawback is it is slow. But Tyranitar is bulky and can carry some damage. FB is similar but less damage and it's slow as hell. Still very usable but obviously inferior to the other two sets.

For defense, honestly it hardly matters. At least crunch may come out but it's pretty dodge-able. If it does hit the opposing Pokémon is in trouble.

All movesets are good for either defence or offense, none are bad for both.
Also, moveset doesn't affect gym placement, so just evolve it anyway.

Evolved 3
B/FB
IT/FB
IT/C
Now decided to stop rolling the dice and power up the IT/C one instead. It's difficult here to get candy from catching.

If you have a competitive gym scene, having a high CP is usually the most important factor for any defender except Blissey. Tyranitar has the highest base CP in the game, so your Tyranitar will likely be your highest CP defender, regardless of what moveset you get and will be a great addition to your defender lineup.

If you want an attacker, then moveset does matter. B/SE is amazing. One could make a case for B/SE being the best attacker in the game, especially for players who are big on dodging. However, several of the other movesets also can be useful for attacking, especially against the game's toughest defender -- Blissey.

The article at https://articles.pokebattler.com/2017/06/05/the-best-blissey-counters-considering-sub-optimal-movesets-with-realistic-dodging-pro/ compares how different mons and movesets simulate against Blissey. B/SE is best by a good margin, but B/C and B/FB are also ranked higher than all other mons/movesets except DB/DC and DT/O Dragonite. Even IT/SE and IT/C may be useful.

"Did yours get what you wanted?"

I speak from experience. I've evolved several. My 2nd was a 98% IV with B/SE, which has become my most important attacker and highest CP mon. The others mostly go in gyms since some gyms in my area require a 3100+ CP to hold a decent gym position. 3100 CP is only a level ~30 Tyranitar, so I can get the gym position without huge stardust/candy investment.

I know this is getting repetitive and anoing. But wait a week or two and see if any news of the gym rework hits. Also if not please don't put Tyranitars in gyms. He is a great attacker. He sucks at defending. He is actually the worst of the big 7. So please just stick to pokemon like Vaporeon, Snorlax, Blissey, and even Dragonite if there aren't to many in that specific gym.

My advice: appreciation, not expectation.

I chose to evolve mine, got Bite/Fire Blast. Someone expecting the best moveset would be disappointed. I had no expectation, and now appreciate it as a symbol of the effort and progress I put into getting there.

Now I'll choose to try for another! And will enjoy the challenge of collecting and hatching while I make progress.

As a proud owner of a 97% SW/HB Dragonite, I really think it's just more useful to stick T-rex in a gym and forget about it...At that point, movesets matter little since any half decent trainer will knock out Blissey, Snorlax easily...

As great as T-rex is, I still think Machamp is the go to guy against any Blissey or Snorlax...He just does it so much faster and for me at least, time is worth more than possibly trying to deal with 2 Blisseys in a row...

Unless you are swimming in defenders with very high CP, it seems a wiser choice to just stick it in a gym and "win" that way.

If Machamp falls, you follow up with Eggs and any Blissey is toast. At least that's how I've been doing it and I battle 2900-3000+ Blisseys daily.

My views are, of course, all from a free 2 play player so assuming you have stagnant gyms and are on the dominant team in where you play (either home/work), that T-rex CP is just so much higher and you will avoid near all shaving.

TL:DR - Overall, I still think Machamp is better for Blissey. T-rex is better in gyms earning you coins and dust. Don't worry about movesets for defenders you can't control.

Took a long time to gather candies. Just evolved the 2nd, Bite + Fire Blast. Was only dismayed for a few moments, then moved on. The first was quite good: 96% with Iron Tail + Crunch, which I maxed to 3595. Over time, I will do many, many evolves. So, I don't linger over a bad evolve anymore.

This game involves a lot of luck. Good luck to you.

Just wait a while. After gym rebalance it might turn out that Tyranitar will be an attacker only.

I´ve got two of them and have been really lucky. Both 87% iv, first got B/SE and second got IT/C.

At the moment both sit nicely at the top end of most gyms I put them into, but when attacking B/SE is in another league than IT/C. Especially with Blisseys, once you´ve hit them with B/SE it´s just frustrating dealing with IT/C. Slow attacking and long cooldown times. Missing a lot of attacks out of fear of charge moves during cooldown.

You power this guy up for the CP, simple as that. If you have a low to middling level (32-33), powering up a tyranitar into the 3350+ range might be your only chance to gain access to the middle to low rungs of a level 10 gym.
