An mk2 evo is great at that when paired with a balanced 2nd stage — just don’t rush buying it; maybe even look for a good deal on a used one
As @Nemrod said, the evo has the advantage of a replaceable orifice so it can be easily restored to tip-top condition
I'd get the the mk11/c370. No reason to get the MK2 especially considering that the price difference is very little. You may end up leaving the Titans as the spares and using the mk11 as the main regulator. The c370 is an awesome second stage.
The Mark 2 is a simpler regulator, fewer parts and is used worldwide in rental fleets. It is also superbly reliable and abuse tolerent. The OP was asking for the most well known "standard" regulator and the Mark 2 is about as close to a standard as there is. Easy to service, if it ever needs service.I'd get the the mk11/c370.

I am currently diving a Mark 11, G250, DGX BCI* and a Mark 2E with G250s. The Mark 11 is a great reg, small, lightweight, excellent performance. But it has more parts in comparison to the Mark 2E. I am diving the Mark 2E for it's simplicity and reliability, not price or performance.
I used a C370 in a pool with a class, my only experience with it. Isn't the air barrel plastic? I guess it does not matter.
(*) Further explanation edit. The reason I bought the Mark 11 was because I wanted a first stage that was as small and light as the Mark 2E or nearly so but which was balanced so I could use it with my DGX BCI. The BCI is not balanced and while it worked well with the Mark 2 Evo I could tell a difference at low tank pressures, unlike with the balanced G250 primary. I am not a proponent of an unbalanced first with an unbalanced second. I know Scubapro and others have and do sell such combinations and they are adequate for their intended purpose, just not for my purpose.

Yes sir, that was the event that caused me to go this direction. It is a little easier to doff and don, fewer pieces and hoses and travel lighter as a bonus and the 40 inches hose is under my arm, not around my neck. But I still dive primary and secondary sets also. But, yes, I think you are remembering correctly.
Yes, I was using a long hose wrapped around my torso and neck. The crew was in a hurry, I still had my camera and was trying to hand it off and they just grabbed me by the long hose and my bad arm and yanked me in while I was still trying to doff my gear being hindered by also still having my camera. The long hose took my mask off. Fortunately another of the divers grabbed my camera, I grabbed my mask and my arm, well, it was sort of mostly still attached

I was coming in from a dive once with a long primary wrapped around my torso and neck and was very low on air. The surf had come up and when I crossed the kelp line on my back because I had no snorkel, some kelp grabbed my tank valve and grabbed the long hose from behind and pulled it out of my mouth. I was pinned down on the ocean floor and I had 4 foot waves going over me. My mask flooded and I tried to find my necklaced back up which had rotated around the back of my neck, it was absolute chaos until another big wave came and ripped me loose and sent me into the cove where my buddy had to come in and drag me out. I had an epiphany right then and there, I vowed never again to use long hose wrapped around my body and neck. Worst idea ever for Northern California shore diving in kelp!

You will need to decide that for yourself. The majority of first stages are balanced these days. My testing with the DGX BCI and the Mark 2E proved to my satisfaction that the combo would work well enough for the intended purpose even at lower tank pressures. However, I found the DGX BCI to prefer a stable supply pressure for uniform performance from full to empty. Thus my teaming it with a G250 and Mark 11 leaving my Mark 2E still with dual G250s and long hose primary donate.
I think I would purchase (and did) the DGX BCI over similar devices for several reasons.
1) parts support to the user
2) screw on connection allowing easy and quick removal to stow with reg set
3) DGX has been in the game a while and are reliable marketer of good equipment
4) price is right
The Atomic and the Scubapro I think are balanced, not super familiar with them so do your research if moving that way.
