Which would you consider the better for AMP. Myself having been around like RI but have tried a number of MA ones and they are iffy.

RI has by far and away the best AMPs as well as the most options.  NMS and Admiral are both non-FS with good massages and table showers.  Pretty much the remaining ones are FS with TS as well.  Can't go really wrong with most of them.  My personal favorite is Pleasant St. in Pawtucket due to one great provider there.
