I am thinking of having my garage floor coated by either a Rustoleum product
(installed by Home Depot) or by Premier Garage - I can not figure out if the
material is any different.

Both companies offer similar descriptions including preparation of grinding
and etching.

Anybody have any reason other than price to pick between them or experience
with doing this in the first place?

Never accept anything for your garage floor except a two part epoxy
system. Acid etching is used for fairly new concrete, serious grime
cutting chemicals for older floors. Solvent based epoxy systems are
more durable, water based OK for typical light traffic residential
garage floors. The epoxy formulations are well proven in most cases.
Sherwin-Williams has a good one, many others are in the market. Prep
and painting are somewhat labor intensive and if the floor is in
decent shape no grinding is needed unless some drainage problems must
be corrected. Off hand, my gut feeling is that this may be an attempt
to extract more profit from a simple paint job than is warranted by
the conditions.
