I have a Leshiy, Veles, and now R5M from Ed... these things are built to last and are dead nuts out of the box... and at this price range, that shouldn't be a nice to have... it should be a requirement. You don't see any posts about them breaking or any issues for that matter. People who do have issues don't post about about it b/c they they did some mod to it (me included)... ie it's on them.
Open the box, adjust hammer (reg on the Leshiy if you're changing cal) and shoot... for a really long time. That is something that gave me peace of mind, and I think is important when spending $2K on an airgun!
The R5M is out of the box ready... you can just adjust the hammer to your liking, but really no need to even touch the reg... and the thing shoots lasers. I've shot single hole groups at 30 yards (i.e. backyard pesting) at 525 - 900 FPS w/o touching the reg. I shoot rats between the eyes time after time (mostly on film too

with all 3 EdGun's I own at 8-30 yards. It's almost boring to be honest how accurate it is. The Leshiy requires some practice with the hold, but the R5M requirements are the ability to pull the trigger. For giggles I've been trying to shoot offhand sometimes on rats to practice my breathing.
The attention to detail is extraordinary in everything Ed makes... and the R5M platform is no different. I've seen a few recent posts about the R5 on here that kind of make me laugh... like FX is paying more folks than just the usual suspects

... I tease I tease! Anyway, the double sided cocking lever has something like 6 ball bearings in it. Can you breath on it and have it cock?... no, but it's smooth AF with a little pressure greater than a 8 year old can do, and I guarantee you... this one won't break!
The trigger is fully adjustable, but I've left it as is for now. I use this thing to kill sh!t in my backyard, not punch paper... so those crazy light triggers are not my jam. You can adjust it though... so dial it in to your liking.
I can't speak for the other gun... but I can assure you, a) The R5M is worth every penny, and b) you will experience ZERO buyers remorse.
Not to throw a wrench into your plans... but I'm hearing the Leyla 2.0 is spectacular as well. I was going back and forth between that and the R5M Standard, but I prefer to shoot off a bipod, and let that be the deciding factor. If you shoot offhand, or off a bag (or any rest)... it's something you should look at too. The laminate stocks Brian has in are sexy as hell IMO, but it's 2 bolts if you ever want to change (on the R5 as well).
Anyways, just wanted to give you some comfort if you go the Edgun route... it's expensive I get it, but you get what you pay for, and you'll have this one throwing lead for a very long time.
Happy shooting!

Here's some video highlights of the R5M... from unboxing to throwing 34gr'ers at squirrels
