I really like how my little crush sounds that I use as a practice amp...but the vypyr has more features so I'd go that route for sure.

The crush is great if you need a portable battery powered amp, or something super quiet for a dorm room to just sit on your desk and jam along with your laptop. The headphone jack is a great touch, and the built in tuner is basically the best thing ever. It's great for traveling, hotels, stuff like that.

Get the peavey if you need a real practice amp for a bedroom where you don't need super duper quiet volumes, but it might even have its own headphone jack. If you want built in effects and don't mind plugging into the wall for power, that's the way to go.
