While I couldn't find an image of the M959ED on the web, I found its instruction manual. I note that it takes the same stylus and has identical specs to the M95ED. So it is effectively an M95ED. This is a great cartridge that is well worth investing in with a high-quality replacement stylus.
The 2M Red is not quite in the same class as the M95ED, as the latter has a nude elliptical stylus while the Red has only has a bonded elliptical. Having said that, if you get a replacement aftermarket stylus for the M95, it is likely to be bonded, unless you buy an Analogis Black Diamond (or similar Swiss-made nude stylus), or go all the way to a Jico SAS. But I think the superiority of the M95ED over the 2M Red also shows through in the sound.
A mention of the 2M Red stirs up strong negative emotions in some people, while others love it. In my experience, it is not a bad cartridge - it is actually remarkably good at some things. It's detailed for the price and delivers music with impressive dynamics. It falls down a bit on refinement and subtlety - sometimes it can sound abrasive and is not an easy listen. An upgrade to the 2M Blue stylus may address some of the Red's issues by providing more refinement.
I think you'd find also find the M95ED quite lively and detailed (with the right stylus), but with a more refined delivery that is easier to live with. I find that with the original stylus it has a very attractive, almost addictive sound. But with an aftermarket stylus, you take your chances - I would make sure you buy a Japanese-made stylus such as a Jico or Tonar, possibly one with hyper-elliptical profile.
You also mention the AT-VM95ML. I have less experience with this cartridge (only got one a little while ago) but it is certainly worthy of consideration. My impression is that it's more laid-back than the 2M Red and M95ED in terms of dynamics, but certainly more refined than the 2M Red. I still prefer my M95ED. However, AT's MicroLine stylus is an excellent tracker - very clean and virtually disposes of sibilance - and will certainly beat the bonded elliptical of the 2M Red and possibly even the fanciest of aftermarket styli for the M95.
