Well, Lone_Sheep_Dog, let's see... Worth the money? Fun? Maybe the wrong way to look at it or the wrong questions.
I bought one of the EOTechs for my SHTF semi-auto .308 rifle. IF indeed the S__t ever did hit the fan, there is utterly no question in my mind it will have been worth the money. Even if I only ever get into one life-or-death shooting situation in my entire life, it will have been worth the money. I'm thinking you've looked at the features and know why they're so good? But the three biggies are fast target acq (you put reticle on target versus lining up four things: your eye, the rear sight, the front sight and the target), head-up both-eyes-open situational awarenes and variable lighted reticle for low/no light. The first two, with the 64/2 MOA circle-dot reticle, make it very possible to lead and hit moving targets (how many SHTF shots will be stationary? - at most, the first one, maybe).
But you asked, "Worth the money for just target shooting?" Uhhhh, probably "No." But, I have had fun practicing with the EOTech for SHTF situations, such as rapid fire on moving targets. That's more open field "play" than paper punching at the range, though. At the range, the EOTech is a easy, reliable paper puncher at the 25-50 yard distances you mentioned with , you guessed it! - 2 MOA repeatability (the same as the inner dot of the reticle). But the EOTech will not do justice to the 300+ yard capability of your 5.56 or my .308. It is not supposed to - it is a 100 yard and less sight (at least with my unaided eyes); maybe 200 yards for "minute of torso" accuracy. [You can get flip-aside 3x or 4x magnifiers for the EOTech, but they cost as much as the holosight itself.]
So, long way of saying, the EOTech is not "fun", unless you juice up the action somehow. Then it's a hoot. It is not fun to punch stationary paper at the closer 1X magnification ranges because it is too easy - no challenge. It is not fun to try to punch paper at 6X and 10X ranges because, with 1X, I can't properly see the target - too challenging. So, to juice it up and get an appropriate and fun challenge, I want to practice standing, off-hand shooting at mid ranges (100-150 yds) to see how close to the (supported) 2 MOA I can get to. Another fun thing is, one of my ranges has timed flip-to-present target holders, with random intervals between presentations. If you start with the rifle at chest carry (or even on a sling over your back), that's a challenge, to get your reaction time faster. Anyway, you get the idea. The EOTech is a deadly tool for close-quarters combat when targets are running, bullets are flying and the shooter is loaded with adrenaline. That's why the military and SWAT teams use it. You take it out of that enviroment to punch hanging paper and, uhhhh, it's not as interesting.
By the way, I don't recall the full history, but the EOTech was developed in the 1950s for civilian shotgunners to shoot birds on the wing. THAT kind of shooting DOES have all those features: moving targets, lots of shooting all at once and good adrenaline flowing!
