I recently ordered the Tamashii R2 from Amazon and it arrived yesterday. After spending a little time with it, I naturally pulled up this thread for a little help with turning on the holo projector. (You really have to turn harder than I would have expected.) My only other complaint was the holo projector on top of his head comes off and needs to be glued back on. I found the comments here interesting reading and thought I would add my take on both the HT and Tamashii... I doubt any of my observations are unique.
Overall, I think both versions have their pros and cons. I don't think one is good and one is bad. I think it all boils down to preference. Having owned multiple full scale R2's, I think the criticisms appear to be carrying over to the 1/6 scale.
Hot Toys pros:
* Obviously the aluminum look to the dome
* R2 blue looks to be more accurate
* Nice weathering if you like your R2 dirty
* Broader variety in sounds
* Some will say dome shape is more accurate. I think this is personal preference.
* Fiber optic light color in front appears to be more accurate.
Hot Toys cons:
* Holo projector light comes on with the other lights and is very bright.
* Audio has a more tinny sound (not a big deal to me)
* No restraining bolt
Tamashii pros:
* R2 feels solid and gives the perception of durability
* Holoprojector light can be turned on separately
* Some will prefer the squeaky clean version
* Kenny Baker feet is a really nice add on not done before.
* Not sure this is a pro, but the dome finish has the look of fiberglass. Many movie R2 dome were made of fiberglass, so not necessarily a bad thing unless you want to see a painted spun metal finish. It's definitely an improvement over the sideshow R2 that looks like a flat gray finish in comparison.
* Overall I think this R2 "fits" better with the Tamashii C-3PO.
Tamashii cons:
* Some will put the rivets at the top of the list, but they don't really bother me. Neither do the small gaps to open the doors.
* Again, some may say the blue is not dead on or the dome shape isn't 100% right, but not a major issue for me.
* Dome finish will not satisfy fans that want a 100% metal look.
* I think what bothers me most is there really needs to be a film placed over the lights. One would have to open the dome as some have done on this forum.
Overall, I don't think you can go wrong with either. I think my preference is with Hot Toys, however, I like the Tamashii better when displayed next to the Tamashii C-3PO
