Having had a very little experience with both the original Vox amps, and the Peavey, (which I just bought for my son
http://www.peavey.com/products/brow...item/116751/number/03584290/Vypyr®30.cfm), I vote Peavey right now. It is too early to tell about quality control issues, but Peavey has a good reputation for making things right, and for being good to deal with. Hopefully I won't have to test that rep anyway.
In my opinion, the new improvements to the Vox series does not justify the extra $$ you have to pay to get a similar modeling amp, and the Peavey's interface, and included tools like a looper, onboard tuner, and the stompboxes and rack effects give it the nod. My son's b-day is not for a few days, so I can't pull it out and really tear into it. However, I did get to play around with it with the aid of the salesperson who is a good guitarist, and together, we dialed in some really nice sounds. Peavey's presets all need to be changed, for my taste anyway, as they tend to be a bit oversaturated, like a lot of mfr's presets when you get a multi pedal. But you can dial in some really nice tones, and the transtube, while not true tube of course, provides nice, warm sounds, and the analog distortion sounds nice and raw and real.
EDIT: Interestingly, the salesperson walked me through how you could rely on the analog distortion of the amp models, (still backing off the saturation in the pre-sets) to get great tones "dry" before adding any stompboxes or rack effects. The stomp boxes are on a knob first in line, because that is typically first in line in the signal chain, then the amp models, then the rack effects that would be more typically applied in an effects loop. All is tweakable with the eq (low, mid, high) and pre and post gain knobs, which also serve as adjustment knobs for the effects. The models are cool, and the engineers notes are interesting as well. It even has a Peavey Classic series model based on the C-50, which is a sound near and dear to my heart.
So for a good full featured modeler, I think Peavey has it going right now, esp. with the price point, as long as they take care of any QC issues that come up. The knobs are on the light side, but that is not a big deal, and the cab seems lighter than my C-30, but looks well constructed. The Vox seems a bit heavier, and with the cheese grater, a bit more industrially constructed at least by feel. The Peavey comes with a blue marvel speaker, which is nice. I also wish that they made the speaker mute when you hook up for recording, via USB for the 75 and up, and headphone jack for the 30, optional, so you could hear yourself play as you recorded, without relying always on the computer sound output.
I am very interested in the tube driven Vypyr 60, but that has not shipped yet. I have no experience with the Line 6 Spyders, but I do like my toneport.
