Not the single row, that makes no sense to me. Why inject the risk of intervention only to get the same materials but less capability of the single row you mentioned.
The 1% was 5 years ago. Age and mileage have increased since then. All rotating parts wear.
I think I'd consider the expertise of the mechanic doing the work as one of the factors helping me make the decision. Right tools, right instructions, any vendor training, experience with the tools and specific bearing I was choosing?
If I was paying for the labor or doing it, the increased parts cost would be a trivial item. Do it once and do it right.
Having said that, I can't tell you the number of cars I've sold that the buyer got 80%+ of the benefit of my investment. Consider how long you think you'll keep the car.
And what else should you do while the transmission is off the engine? The AOS change is a classic choice.
It is easy to spend your money.
