No experience with either of those on a 5.3, but the supercharger on my mustang has a bypass valve that's hooked to a vacuum line and stays open until the vacuum drops to a set point then closes, allowing boost pressure into the intake.
Engine intakes are under vacuum during no or part throttle, then as throttle (or load on the engine) increases the vacuum lessens and will be at 0 at full throttle.

Hope this helps, this is from our tuner who has been running Magnachargers, Whipple and Edelbrock on his daily drivers for years.
Magnacharger and Edelbrock bypasses are set up for smoother boost application.
On his Whipple'd 6.2L, if you are riding right at the edge of boost and increase throttle by just 1%, it can go from 2" vacuum to 2psi of boost instantly, resulting in a bit jerky of a drive.
So my 5.3 with cam, headers, heads rips pretty good from 3500 and up. It is anemic from 0-20. Doing a roll from 20-60 actually pushes me back in the seat. 0-20 feels like it takes longer than 20-40.
I could do a 6.2 or bolt a TVS 2300 on for the same price. Which would you do? 5.3 has 145k on it but has new lifters, oil pump etc.
The thing I like about doing the blower is it's less hassle then tearing the truck back down again.
The thing I like about the 6.2 is it's simple.
Both will net similar gains.

Low mileage 6.2s cost around 3500 to 4k. Maybe recoup 1k from my long block?
I can get the blower setup for around 5k.
Really the labor involved isnt bad for the engine swap. Only thing I am unsure of is how to get the engine up my driveway off the freight truck.

I'd do the blower and if the 5.3 dies in a few years put a 6 2 under it.
Was thinking the same. I am trying to find out from Magnuson what would have to change on the blower for it to fit square port heads if I ended up changing.
