>>49225149I did the same thing. Started in gen 3 around March last year, finished the main dex in october and then got around to grinding out the last few gmax forms I was missing this week.
Similar to
>>49225382 I wanted to finish the whole form dex in each game before moving to the next generation (although I started in 3 and didn't bother with gender differences that weren't counted as forms). There were a few difficult captures that would have been easier if i'd waited until later gens. Having to catch Tauros, Scyther, Pinsir and Chansey in the kanto safari zone was a pain, Surskit was surprisingly rare in Hoenn, and getting all the Floettes was an early-game chore in Kalos (I found a shiny yellow flabebe before I even saw an orange one).
