Time to upgrade my wife's "boyfriend"

Our sex life is mostly me pleasuring my wife with my tongue and her fav. realistic vibrating dildo that we call her "boyfriend" because when we lost her FWB we went on a road trip to all the area sex toy shops and found a toy that reminded her the most of his cock. Her FWB was over twice my size and so is her "boyfriend" (the toy)

I'm wanting to surprise her with a newer "boyfriend" preferably one of the newer dual density silicone models. I've seen a few that are "thrusting". I'm mostly looking at the RealDick models and was wondering if anyone has tried them?
