Has it changed my collecting habits?
Yes and no.
I've only been collecting for about a year now, and I'm far from a completist.
I've got 2 MPs, 2 Movies, 4 Animated Deluxe, 3 U2.0 Deluxe, & 1 U2.0 Voyager.
The MPs were the first TFs I got, and they are frickin' awesome.
The two Bayverse TFs (Brawl & Arcee) are good quality, but their molds were a bit kibble-heavy for my taste.
Then I got my Animateds.
Lockdown was the first, and he had leg issues (which I made worse by trying to fix) and the limp-wrist problem (which was easy enough to fix).
Prowl's legs are loose, but that's forgiveable.
To be quite honest, as much as I like those figures, they were a real turn-off, to the point where I almost stopped collecting.
The other two (Oil Slick & Soundave), being from a later wave, seem far more sturdy.
I had been set on getting them anyway, and I was really relieved that they were of better quality.
So that kind of salvaged my opinion of TFs in general, but not necessarily the Animated Line.
The Universe 2.0 figures (Sunstreaker, Sideswipe, Acid Storm, & Tread Bolt) have really been great.
There's been no real problems with any of them, which makes me want more, which has been rather hard on me in terms of money.

I do have a bit of a theory, though:
The Animated line - which had quite a few issues - was made for American release, right?
The Classics/U2.0 line - which seems to have had less issues of lesser severity - was made with Henkei release in mind, correct?
I'm probably way off base here, but could it be that the Animated line (A) just wasn't as important or (B) was such a change from the norm (e.g., Classics) that it was difficult to adapt the manufacturing process to the Animated style.
