I've said before and will again. Generations exclusive focus on G1 (primarily 84-86) wouldn't bother me so badly if three out of the seven concurrent lines weren't almost exclusively g1 based. And one only pays lipservice to non-g1.
Authentics- exclusively g1
Generations- may as well be exclusively g1
Cyberverse- i think the only non-g1 we get is thanks to the writers fighting for it
Studio Series- movie
Masterpiece- so g1 it hurts. But enough BW and movie that it technically doesn't qualify.
And I'm quite fond of the Alpha (deluxe-sized) Optimus Prime. For eight quid he's a decent figure. To my mind, anyway. But aye, I do wish the Titans were just a little better. I was after a version of that Grimlock design that had jaws that actually open, which they do in the Titan! But the rest of it... is terrible.
