Can't really compare apples to apples for you but I have the ED Matchpro and a Vortex Venom 3x15.
I use them for different things and I'm happy with both of them.
The Matchpro is over a CZ457 24" Varmint on an ACC Chassis and the Venom is on a Kidd Supergrade "gopher gun." I paid $700 for the Venom and got in on the rebate program for the Matchpro last year and paid about the same for that. I feel I really got my money's worth on the Matchpro.
The glass is pretty good on both of them but the Matchpro is better without question. The eyebox on the Matchpro is really tight and the Venom is a little more forgiving. But if you're only shooting off a bench, the eyebox thing really isn't an issue.
I find the "controls" on the Venom to be quite stiff and I'm hoping they'll get a little more responsive with more use.
If I was in the market for another scope (and really, who isn't?) I think I would, as others have suggested, take a look at the Arken 5-25 Gen2. If it stops raining, I might go look at one again this afternoon. LOL
