With Gen 3 are you more content to get just 1 really good one?
I’m not finding the gumption to get more than 1 Gardevoir. Same with Blaziken. Have a great Bagon I’m still working on, but I doubt I’ll be grinding out 3 or 4 Salamence. Looking for a Beldum to eventually power up, but same situation doubt I will bother with more than 1 or 2. Exception might be Hariyama and Sceptile, since they’ve been easier for me to catch.

I feel that none of the big Gen 3 deserve the effort of having more than one. My current plan is evolving one for the pokedex that is above 87% and when possible level higher than 20... And then I'll calm down and just wait patently until get something with amazing IV before evolvng/powering up another.
maybe starters for different type movesets,
one pure fire blaziken, one pure fighting
one water swampert, one ground
Sceptile is simply too good, and I don't like eggs, but depending on community event move I already like venusaur as a grass most
If I ever get candies a second milotic is plausible for different moveset as well.
Salamance and Metagross will be just collectible just as mentioned above aside from sceptile.
one fairy gardevoir will do most probably, If I get candies and a good ralts I would evolve a second one but not shooting for it.
I think think this is probably fairly common for players that have been playing Pokemon Go longer. We already have good teams of attackers for a lot of types, and there is not a lot in Gen3 that exceeds the earlier games.
Each generation of the main games is a closed environment. With Ruby and Sapphire there were a lot of cool pokemon designs, but they also pulled back a little on power level. That is okay in the context of Ruby and Sapphire's story mode, but doesn't translate well to Pokemon Go.
I am keen to get a second Gardevoir, but getting my first Metagross (and Salamence) is more important for now.
If Metagross had better moves, I would like two: one with both Steel moves for attack and the other with a Psychic fast move for defence.
Catching another level 25+ wonder Makuhita is just a matter of time and I will have the candy.
Most of Gen 3 serves as decent alternatives but nothing essential. There are no type-specialists that vastly outperform others in this series. Gardevoir doesn't carry the type-purity or stats to justify it for DPS (it's give-and-take against Fighting types is incredible though). This is also the case with Metagross. Salamence doesn't outright replace Dragonite and is challenged by Rayquaza. The starters are rivals to type specialists but not strictly better.
For this reason, I am maxing out one of each of these for each moveset and none more (i.e. Shadow Ball and DG Gardevoir, Psychic and Steel Metagross)
That being said, gen 3 has the best legendaries thus far, in the weather trio.
I love Gen 3's Pokemon designs. It's a damn shame that the only non-Legendary Hoenn Pokemon I use regularly are Walrein, Sceptile, and Breloom, with Sceptile being the only one that has completely replaced another Pokemon (Exeggcutor) in my battle parties.
I do want a DG Gardevoir to replace one of my Espeons in Machamp raids. I'm in no hurry for a Salamence or a Metagross and it's a good thing because I've found 0 Beldums
