Depends on what you want to do. I hate them. Problem is, when doing anything more than "trail running" (and sometimes even then) you sometimes (or frequently in my case) find yourself needing to go from low to reverse directly and quickly. This might be for "rocking" or getting off a high center, or even to avoid an "endo" or worse. For that reason, I avoid all ratchet shifters AND reverse lock out. In fact, my shifter has been (or rather was in the process of being) modified to provide a "park lock out" to keep from accidentally overshooting reverse. But, I’ve since decided to switch to an Art Carr true gate shifter to avoid missed shifts in the future.
In any case, IMO, ratchet shifters and reverse lock outs belong on the drag strip where there was a need which led to the development of those technologies. The cons for off-road use dramatically outweigh the very limited (IMO) benefits...
