Both are common and about the same on quality. Cast Alloy construction.
Rota has a lot of knock offs in various sizes and weights.
Best part is the variety of finishes.
ASA you can get through tirerack.com (11 designs), contact Alex@tirerack if interested in learning more.
Rims from 15" to 18" diameters.
ASA are Low Pressure cast one piece rims-
LOW PRESSURE CASTING
From tirerack.com:
Low pressure casting uses positive pressure to move the molten aluminum into the mold quicker and achieve a finished product that has improved mechanical properties (more dense) over a gravity cast wheel. Low-pressure casting has a slightly higher production cost over gravity casting. Low pressure is the most common process approved for aluminum wheels sold to the O.E.M. market. Low-pressure cast wheels offer a good value for the aftermarket as well. Some companies offer wheels that are produced under a higher pressure in special casting equipment to create a wheel that is lighter and stronger than a wheel produced in low pressure. Once again in the quest for lighter weight, there is a higher cost associated with the process.
Vs
GRAVITY CASTING
Gravity casting is the most basic process of pouring molten aluminum into a mold utilizing the earth's gravity to fill the mold. Gravity casting offers a very reasonable production cost and is a good method for casting designs that are more visually oriented or when reducing weight is not a primary concern. Since the process relies on gravity to fill the mold, the aluminum is not as densely packed in the mold as some other casting processes. Often gravity cast wheels will have a higher weight to achieve the required strength.
For Rota wheels:

Superior casting using two distinct methods: low-pressure and gravity die-casting
Low-pressure die-casting - involves filling the mold with molten aluminum by pressurizing from the bottom. This represents the latest casting technology.
Gravity die-casting - inovlves filling the mold by pouring molten aluminum from the top. Currently the most widely used casting process.

considering tirerack carries the ASA's, i think they are top quality
even if they are just casted cheep wheels.
quality in terms of paint durability.
if ASA, SportEdition, and Rota made the same designs i would take
SportEdition though. ive had those in the past as winter wheels and
they were OE quality.

Always good info from Minihune!

Love my Rota's ! Inexpensive, good looking and very light weight. I went with Rota Slipstreams in a 16x7, 13.5lb's. I had a set of ASA's AR1's on my MR2 and liked the fit and finish but at the time, I didn't really know about the difference that weight can make with performance. Here's an old shot of my "MR 2". I really like'd the look of those wheels. I really miss that car !
