Don't have any experience with the MXR, but I can offer you some insight on the VT and Agro.
First of all for reference, I've had these recorded.
'62 Jazz RI played with a pick:

I recorded these comparing a slight gain, a heavy gain, and an extremely heavy gain with both pedals. Sorry for the length, but I recorded them in this order on both clips:
1. Flat Jazz
2. VT (Low gain)
3. Agro (Low gain)
4. Flat Jazz (to remember original tone)
5. VT (heavy gain)
6. Agro (heavy gain)
7. Flat Jazz (again for clean reference)
8. VT (extremely high gain)
9. Agro (extremely high gain)
For personal experience with both pedals I can agree with previous comments. The VT records really well solo, but I have had a harder time putting it in front of an amp and still achieving great results. The Agro seems to play nicer in front of an amp, but as mentioned there is some low end loss. The VT will obviously color your sound a bit (as it is an Ampeg emulator), and the Agro will a
little less. The Agro does seem to sit more on the side of a distortion, rather than a drive, but obviously both are subjective depending on what you dial in.
The VT's controls are way more touchy than the Agro's (I would find myself knocking my controls in transport and having a harder time dialing back in my tone. As far as tone - the Agro is a neater OD in my opinion. It's a really precise OD. It cuts
through the mix well, but I find it harder trying to sit
in the mix. The VT gets sloppier with all sort of great overtones that can
beef up a signal as opposed to making it slice. So I would say it varies on what you are looking for.
Both have been a good tool for recording (with a clean signal mixed in), but the Agro is the one that sits on my pedal board, where the VT doesn't anymore. And with all that being said, my Distortron is still my drive of choice over my Agro for the majority of what I play. I love the tones with the Agro, but I'm still trying to find its niche. The VT I use to experiment with these days.
Maybe some of this will help...
