Even limiting to five I have to dip in to the ones I'm mostly taking a passing interest in. Really I have a top two:

Peercoin (PPC) I still love SHA but add in PoS and I like it even more.
Digitalcoin (DGC) Developer has put a lot of effort and resources into building trading and marketplace sites. Baritus gets that it's not really a currency if no one actually buys and sells stuff with it.

Then I get into coins about which I have interest in and am watching but for whatever reasons I'm not enthused about:

Namecoin (NMC) Great proof of concept (using the blockchain for practical purposes) and I shouldn't be disappointed if they haven't done more, but as a currency? Meh.
Vertcoin (VTC) Seems to be fighting ASICs the right way. Interesting. Plus it's green.

Then we have "honorable mention" which are coin I like for some reason or another but not enough to really take seriously. I've bought or mined these because I was amused or interested, and I keep my eye on them but ultimately they are nothing special to me. Maybe they have a name or a logo that I could see people using (sorry, so many coins out there won't even be adopted because their names have unfortunate implications) or some kind of buzz going around that caught my attention. I'm listing more than one because all together they all fit into the category of "other." I'm really just too lazy to pick one.

RonPaulcoin (RPC) Yeah, it's Dogecoin with a different meme.
Smartcoin (SMC) Um. Honestly, I think it's just because I find the logo soothing.
Saturncoin (SAT) Everyone's favorite planet, right?
Securecoin (SRC) If you like Quark's technology but hate Quark, then Securecoin is for you.

Now how about the ones I'm actively disinterested in?

• Litecoin. Sorry, but I think adoption of a currency by people in general is important. Nobody wants their money to be less filling but tastes great. The name fails to inspire confidence.
• Feathercoin. See Litecoin.
• Terracoin. Too many forks to continue trusting. And sounds like "Terrorcoin" so, no.
• Novacoin. Used by your dentist during your root canal.
• Phoenixcoin. Really? You want to inspire confidence in your coin by invoking a mythical creature that burns itself to death periodically?
• Casinocoin. Because currency really ought to be used for only one thing in one context. Riiiight.
• Dogecoin. Yeah, we've all had our fun.
• Maxcoin. Cult of personality. Yawn.
• Devcoin. Can someone explain to me why Devcoin is somehow more "ethical" than other currencies? It's different because it is made for trading in services. Uh, yeah. You're saying it's more ethical than other currencies and unique unlike other currencies because it is a currency. Basicallly, see Casinocoin.
• Mincoin. See Feathercoin.
• Freicoin. Special contempt for Freicoin for one reason: demurrage. A little knowledge of economics is a pathetic and dangerous thing. Here's a cryptocurrency that managed to build in all the worst aspects of fiat currency. Yeah, thanks for the nifty fruitcake, it was delicious. Really, yes, I ate the whole thing.
