SBRT is no more modern or less risky than IMRT. It just delivers more radiation per dose, so that fewer doses are needed. SBRT is a form of IMRT. I would much rather have IMRT from a great center than SBRT from a so-so center and vice versa.
Basically any machine that delivers IMRT/IGRT SBRT are going to be equally safe. The Varian class machines use a method where they continuousy deliver the radiation while the gantry is moving around the body. Other machines do a start and stop method. The Varian is not safer, per se, it is just faster. I was treated by an Elekta IMRT machine and it would take about
10 minutes per treatment because the radiation was delivered from 9 different positions of the gantry. The radiation was delivered only when the gantry was in a fixed position. A friend had IMRT from a Varian machine and his routine was about
six minutes. We both received the same amount of radiation and experienced very similar side effects. His only advantage was time. The advantage to the radiation center was they could treat more people in the same amount of time and thus make more money. Technology development isn't just oriented for client effectiveness, but also provider income.
As to choosing the center, they will all have to follow the same accepted protocols for safety. Make sure your local center is well regarded and does a lot of PCa work. If so, then the convenience will be valuable. If they have only done a handful of SRT procedures this year, I would go where they are delivering radiation to treat PCa every day. With IMRT/IGRT/SBRT it is the people, not the brand of the machine that is the most important factor.
