*****Spoony tops my list, even if he has left. I've watched his stuff more than the others combined, and I enjoy his high-energy performances. He puts a lot of effort into his videos, and it shows. When I need a good laugh, I go to Spoony and watch something like his Wing Commander review. His ability to carve a stinger out of filthy language is a thing to behold.
****Nostalgia Critic is second. He's not always laugh-out-loud hilarious like Spoony can be, but he's consistent enough that if I have some free time I will put on a few of his vids.
***Lupa is third. Aside from the recent "scandal," her stuff is pretty funny. Her comedy is different from the others on the site - she digs the horrible movies and loves the cheese, as opposed to figuring out how to hate it. She's also pretty consistently hilarious, but the bits with her cat aren't that funny to me, and while I respect her apparent relationship with Phelous, I don't think the two should have done their recent team up.
**Todd. Aside from his (often spot-on) hate for a certain artist occasionally taking up an entire episode, he's hilarious. Once more, he obviously understands music much better than I do, and I learn from him. Two thumbs up.
*Linkara wins last. I don't always laugh at his stuff, but I respect his professionalism and dedication to his values. He puts in a lot of work to make sure he delivers a quality product, and he's one of the few who have done more than upgrade their cameras and microphones over the years. I still don't want to pick up a comic book or re-watch Power Rangers, but he gives both mediums an air of respect.
Honorable Mentions: NChick/Snob. Both are good on occasion, but I don't really rewatch their stuff. It's usually analytical enough that I don't need to see it again, or just bizarre enough that the jokes really are one-two punches that I won't laugh at again.
The only one that dips below mediocrity for me is Phelous. I think his voice is grating, and while he's fine for cameos, his sense of humor is pretty antithetical to mine. He just seems to have the one mode, and it's not my bag.
