The reviewers I like are Firestarter, MMPRtoys, ShukenShinobi, and K2eizo.

Oh yeah I forgot the japanese ones. My favorite of those is by far leonchannel.

I admire TJOmega so much for his very detailed analyses on Toku toys. But since he doesn't collect everything from a season I don't get to hear his thoughts on certain toylines as a whole. I dig the RRR YouTube channels alot because they're more likely to see a line through. Hassan Ahmed does great PR/SS stuff as well, hope he gets more support.

Zeron, TJ, and Vangelus are three of my favourites- I do enjoy Peaugh's reviews but prefer his TF vids to his toku ones.
Digger318, however, is becoming a favourite more and more by the day- especially for current stuff, as he reviews things pretty darned quick and generally comes to a good conclusion regarding value for money.
K2eizo is my preferred japanese reviewer, along with CSToys' Mr. S, if he counts.
Having said all that, I can't think of any reviewers that I actively dislike.

MMPRToys and ZeronXepher.

I don't watch Toku reviews too often, but Vangelus is my favorite when I do. I enjoy Peaugh's stuff as well.

in the TF realm, Vange1us for laughs and Peaugh for technical stuff like transformation details

Toku wise, peaugh doesn't do much for me, seems kinda lifeless when reviewing SHF. Vange1us is awesome but too low volume of late

I watch ShukenShinobi and Peaugh for reveiws of newer things that I'm interested in, and watch Vangelus and TJ Omega more for the entertainment values of their reviews.
