Okay, so i was writing, and getting a response while writing meant "Time to rewrite" xD
The main wallet I use is for OTC trades on the #bitcoin-otc IRC channel, and that never has lots of coin. It has an extremely fluid balance because I never hold coin there for long. If there's little risk because of the fluidity of the funds, then I'll probably use that on blockchain.info indefinitely. (although since it's a vanity address, I can import the privkey to a bitcoin-qt client at my leisure).
But, I want to be able to receive donations on one of my sites, hence wanting access to the wallet from anywhere and not needing a bitcoin-qt or similar client. If it were *your* choice between a web wallet or a bitcoin-qt client running 24/7 for the purposes of receiving bitcoin, which would you choose for the specific case here?
***EDIT: I missed BitcoinBoss's answer when I was writing this. But the open question still remains
