I use the CWTN plugins for all my toons when available. For others I prefer RG mercs for while I am leveling and grinding AA because it will adapt and grow with you. Get a new spells and AA? RGMerc will use it. If you are using KISS you need to edit your ini file as you level and gain AA and that can be tedious. For my bard, he is max level and max AA so I have a good KISS ini that I use for him.
