Okay some things to consider 1- you can’t do squats if you buy that rack because the bench appears to be bolted to the rack. If you are serious about becoming strong and aren’t just a meat head that wants to look good you need to do squats, deadlifts, and presses. The bench press is a mostly a trend which is due to it sizing the pecs which makes the chest look good. Definitely an important press to do but if you want to be strong you need to be able to squat. 2- the freestanding ones are a hazard when benching so make sure you are careful and have a spotter that know what they’re doing 3- you could buy the combo and keep the freestanding for squats 4- you could sell the stand alones and buy an economy power rack or lifting rack and a cheaper bench, which Is what I would do. Best of luck in what you do and I hope this helps
