Newbie question about ladder sights

[C.M.Roy]

Hello. I have been out shooting and I got a hankering to put some long range sights on my 1895 cowboy. I am going with the ladder style sights because the tang style sights effect the way I hold the rifle. So I did some foot work and have narrowed it down to these sights (all of these are on the buffalo arms site. I am using the buffalo arms site only for picture purposes)

1. Smith Barrel Sight - Smith Buckhorn Rear Sight Extra Long Range 3/8" DT
2. Smith Barrel Sight - Smith Marlin Model 95 Sight 3/8" Dovetail
3. Ukrainian Barrel Sights - Win Ladder Sight 3/8" Dovetail with Long Staff

The main attributes I am looking for is strength, elevation adjustment and holding power of the sliding sight on the ladder. Thanks for any help.
