Basset, Sadlak, Smith, and ARMS are going to be your best bets.
The Basset is nice as it is one screw, it's repeatable as long as you follow the instructions, and you can easily remove it for irons. The low mounts will not let you use your irons while installed, so that might be or thing for you. The high mounts do, but your optic is going to be way up there. Even with the low mount you will probably still want a riser like a Bradley if you are using a conventional stock. On a VLTOR type stock you can bring it up high enough that you probably won't need one. The radius on the mount may interfere with some optics rings/bases. I tried using the Basset for my MRO/magnifier and because of the profile on the radius I couldn't get the magnifier on there. There were a couple of other QD/throw lever type mounts that wouldn't work on it either.
The Sadlak will let you use it with a wide range of receivers that may be out of spec. They have a measuring/install kit you can use to measure your receiver and they will machine your mount to fit. They're also pretty durable.
The Smith is a good mount from what I have heard/seen as well.
The ARMS is good as well, so long as it fits your rifle. Some receivers don't work well with it. It will allow the lowest mount possible and when installed it looks like it is part of the receiver. Sometimes that low height means you have brass being caught up between the op rod handle and the bottom of the mount/rings, but you can use GI bolt parts, trim your ejector spring back, or a few other things to get around that if it happens. You can also find one of the split versions or send it to have the middle machined out.
There are some other rails out there that are not easy to find.
The VLTOR handguard rail is good but you may not want to go that far out.
The M14.CA mount is another option. It requires the removal of the rear sight assembly, and then mounts to the sight ears and has a pad that comes down on the receiver, similar to others. It does get the scope down, but at the cost of your irons if that is a concern. There is a hole in the rear of the mount and a channel through the rail to allow for using the front sight if you really need to up close.
The SAI mounts have either a love or hate response from users from what I've seen. You are supposed to beat the mount to fit it to your receiver (if I understand it right, it is a more brutal version of what Sadlak does). The aluminum keys that fit into the locating recesses are forced into mating when you hammer on the mount. The you have the rear screw pushing/pulling to give you some windage adjustment before you use the adjustments on the scope. Once you have it set, then you lock it down. There are lots of reports of these coming loose, but there are also lots of reports of people mounting them 20 years ago and being fine.
