Being a selective collector I do a fair amount of research on a potential addition to my collection.
Text based reviews are the best, coupled with quality photos showing whats important to enhance the text. I am also a big fan of pic-heavy reviews (think sibertron galleries) as its easy to get a good look at the figure and save some for further perusal.
Having said that, I often find that there will be some aspect/feature/gimmick/view/etc that is not captured or displayed so I use youtube video review/s to 'fill in the blanks.'
Does that make sense?
EG - there was a figure a little while back, that all I wanted to see was the underside of the alt mode. No reviewer showed or talked about it. I had to use a 20sec portion of a 9min video review to see the angle I wanted.
Short answer = both have merit
