I'll start off with the ever popular:
TL;DR: Very thick, super fast drying, popular, finicky fast dry top coat. It's almost a requirement to buy the Seche Restore at some point if you want continued use of this product.
--China Glaze Fast Forward; This used to be my go-to top coat. Well, it's still my current top coat but I'm not going to buy anymore. I've figured out this to be the offender over a lot of mani problems. Over looking the fact that it doesn't dry very shiny (which may be a good thing for some of you who don't want super shine), it's not very good for multiple layer mani's. The smell seems to linger, and i've figured out this top coat has been the offender behind my pedi's basically fading out. By fading out, I mean the color seems to gradually fade and eventually peel off my toes in a matter of days. It dries OK for just one color mani's. I've went through 4 or 5 bottles of this, I won't be repurchasing sadly. Like Seche Vite, it also goops up about half way down. Which is to be expected sometimes with polish, just figured I'd note that.
TL;DR: Basically, it's a very thin fast drying top coat--not very good for glitter or multiple layer manicures. Lingering smell, fades color sometimes, doesn't dry very shiny.
--China Glaze Matte Magic; This is a really tiny bottle. I really should have checked the size before I ordered online. Caught me by surprise. It's only .325 oz compared to the usual .5 oz. It works pretty well. Though this is probably with all matte top coats, if you use lotion or wash your hands you risk getting shine on your nails and the effect wearing off. Just something I figured I would note. If you're wanting a matte, I'd go with Essie's Matte About You--that seems to be the go-to matte top coat in nail polish communities.
--Out the Door; Another fast dry top coat. Currently my #1 favorite. I have yet to experience shrinkage like Seche Vite, and it seems to be thick like Seche as well. Which I like a lot when I put glitter on my nails and multiple layers. The smell doesn't linger like China Glazes, and it's not as powerful and overwhelming as other top coats I've posted about. (It's usually cheaper than Seche--another pro!) If you tend to pick or bite your nails, it does seem to peel off in sheets if you overflood your cuticles or pick at them. I think that comes with all thick top coats though. If you have a streaky polish, this seems to help that a bit as well.
TL;DR: Favorite top coat, thick, no shrinkage, fast dry
--Sally Hansen Insta-Dry (red bottle); Another favorite of mine, it's on par with Seche and Out the Door if you ask me. It's easier to find and you don't have to make a special trip to beauty supply stores for it. I found mine at good ole Walmart. The bottle is absolutely ugly in my opinion, but the product is excellent. A thick fast dry top coat.
TL;DR: Second favorite top coat, easy to find, ugly bottle, thick fast dry
OTHER TOP COATS OF INTEREST:
Essie's Good To Go Fast dry top coat: I haven't heard much about it honestly, but it seems to be a top coat that isn't talked about much. May be something to look into if you're a fan of Essie.
Orly's Glosser - High shine non fast dry top coat. I don't know much about this either.
Orly's Sec N Dry & In A Snap - Again, I don't know much about them but they're both apparently fast dry top coats. I figured I would list all of the top coats I know of here. Not pictured. I'm sure I'm missing some, but these are the main ones I read about on nail polish forums and the like.
