Never having handled the Tactipulls, I can't talk about their reliability, but I have had some experience with the Ranger Plates on the LAR-15s, and would go that route again if I still had any LARs.
The only "issue" with the Ranger Plates is that once installed, they will limit the capacity of the LARs to 9. This can be overcome by dremelling 5mm of the bottom of each end of the follower, which will allow you to load 10 and still seat the mag on a closed bolt.
The 10 shot LAR doesn't really need the full length of the anti-tilt follower, so it does not cause any issues, but throw away your original base plates, to stop you from being tempted to put them back on, as you may run into capacity issues,if you know what I mean.
Regards.
