boosted raid trophies vs high IV not boosted?

What’s a boosted trophy?

If you're asking should I power up the boosted one or the higher IV one, I would argue for the boosted one.

At this point, anything I invest dust into I plan to use forever. I'm okay with committing the extra 30 or so candies to get the best one.

Personally I only power up (invest in) IVs of 90% (minimum of 41/45 total stats; if it has a 10 in any stat, I’ll pass).

I had a similar situation with Ho-oh. I would normally power up the highest IV of each species. Caught a normal 93% 12/15/15 then caught a boosted 91% 14/13/14 later on.

What made my decision to go with investing in the boosted one despite lower IV distribution was the fact that the boosted one would result in a higher CP even though it was lower in overall IVs at max level of 40.

If my 93% would’ve yielded a higher CP despite the savings of sources, I would’ve invested in it it but the final CP was what made me go with the boosted one.

I stood before that question myself, having caught Groudons with 15/14/14 (boosted) and 14/15/15 (not boosted) during the first days.
The answer presented itself a week later when I caught a 15/15/15 (not boosted), which I powered up to the max.
Otherwise, it's a tough question. Depends on the fact if you value 15 attack very much. I would probably prefer to power up the high IV Pokemon.

I always value higher base level to save stardust. Aside that for Kyogre i can't because it doesn't rain until around a week later, And for absol or alakazam i never saw these raids appearing in their respective weather (Fog and Windy) so i cannot.

There is no "correct" answer here because it's a sliding scale of need for each player as well as what exactly are we comparing, how much is going to be invested, what are your other options, what level the player is, etc.

My current rules of thumb for the new meta are:
1) Priority is given to 100% if available no matter the level
2) For legendaries maxing highest IV available (preference on 15A, but not necessary), for non-legendary only maxing if 100% or 98%
3) For going only to 30 (e.g. 2nd Groudon, 3rd-4th Kyogre, 6th golem/ttar), boosted gets preference (preference on 15A if available)
4) if it's a common boost (in my area sunny or partly cloudy) then no lv 20 unless 100% or immediate need, if rare (snow, fog) then lv20 is acceptable
