I took the AR on my Infiltrator. I feel that the Infiltrator can be a good sniper regardless of the widow. And I don't like to sit and snipe so I use the Viper and the GPR. No complaints
Personal preference, of course. In scheme of argument pertaining to superiority, preference negligible: widow more efficient.
However, if personal preference linked to success, decision to take AR sensible. Also, point is to have fun; AR more fun, choose AR. Only sensible conclusion.
Viper nice addition for Sentinels. Extends Sentinel's range beyond that of his own powers, or his Tempest. A lot of ammo, too. Very helpful backup weapon.
Infiltrators...Excel at headshots on unsuspecting enemies. Widow clearly superior to Viper in this respect. Almost used Viper/AR's once, changed mind at last minute, went with Widow. Better weapon.
Again, personal preference and individual skill supersede any arguments, yet discussion of which is a more efficient weapon yields Widow as victory. AR's a bit redundant, given similarities between most AR's and Tempest. If you want Vindicator, perhaps understandable.
Anyway, do what's most fun for you. All that matters, really.
