I have experiences with all 3. All of the V1s are total s__t and I swapped all my early Iminime figs over to TTM18s (Mills, Somerset, Ra's, Neo, Smith), although they were slightly improved by tightening them yourself. Iminime's Lecter is on a V2 (I believe) and is acceptable. RMs Plainview is on a V2 and is also acceptable if your talking about the tightness of the joints. The reason why I b__ched at the time was because it wasn't acceptable to me for the price point, but I understand that Plainview was made in that in between period and there was a drought of official 18s at the time. Beto's Beetlejuice is on what I imagine is a V3 and it's definitely acceptable.
Don't let Enterbay's name brand fool you. There were tons of complaints about QC issues with this. Just because EB made it doesn't mean that it's tight and perfect. Wobbly knees plague the MIB sets just like they did with HT Jack Joker.
In this case not only will these KO bodies have tighter joints than the EB but it respects Jules' physique better in every way. It reall is a no brainier. There isn't a better option out there in abundance OR in small quantities.
