I like both figures, both have excellent quality, but I prefer the Enterbay Begins.
Both needed heavy modding and I really like to mod my figures the way I want them. I got the best from the Enterbay, it looks perfect to me now, but I am stuck with Hot Toys.
I just can't stand the undersize cowl and neck. The sculpt is great, no doubt, but the cowl looks so tiny specially from the side.
The only option for it to look best is a bigger cowl, but that is a mod I can't do. I had the crazy idea of cutting one of the Enterbay's cowl neck and with some sanding and resculpting, achieving a similar TDK cowl. Too risky and time consuming. I just hope some of the brilliant sculptors on the forum make a new neck and cowl. I hate Hot Toys for not making the perfect TDKR figure after so many attempts, even if they were done in 1/6.
Enterbay just got one chance for a Batman figure and it was a success. And don't forget about the price, Enterbay's is cheaper and justified, can't say the same about Hot Toys.
