Some of the HD/Lowes have a surround display with hinges that is set up like doors. You can see that some of the differences are style but others are thickness of the surround. A three piece has less seams to caulk than a 5 piece. Built in soap dishes, shelves, and hand/towel bars are nice but are usually the first place to break. Also some surrounds only work with matching tubs and vice-versa. There is also a variety of heights and depths. Do you have room for a 32" wide tub? How high do you want the surround? Some surrounds get glued over existing wallboard while others attach to studs and have flanges than needs covered by drywall.
Also noticed that the old Sterling surround does not fit a three handle faucet properly due to the curve in the side panel.
There is no single answer. What are your goals with this rental? How extensive a remodel? Are you going down to the studs? How is the old tub and surround installed? Ideally I would think a cast iron tub with a solid surface surround going to the ceiling would be the most durable.
If hiring someone to do this install you should ask them for their experience with surrounds.
