No, not at all. Gen 1 is the second best Generation for the series solely from what a bloody brilliant game it was overall. Even when takin' away the fact that it's the beginning and therefore instawins for series innovation, t'was still a revolutionary video game as a whole and 'specially for handheld games. No Pokegame since has done so much for gaming, not even close, as all future mainstay games play it very safe and refuse t' experiment and innovate.
As such, one could argue that, on a literal scale of comparin' Pokegames without respecting their seniority, Gen 1 is actually better than Colosseum/XD and RSE. The former two are just poorly made games overall, whereas RSE doesn't have the charm all Pokemon games have in some amount; GSC and 'specially RGBY particularly exhibit this charm (and no, I don't mean nostalgia).
The glitches are definitely a result of the team's vidya gaem programming inexperience. GSC, despite bein' released very quickly, had it's code cleaned up very well as well.
