I prefer a outdoor range. Among its many attributes is the potential to be much longer than a indoor. I have a close to 100 yard safe range on my own property and use it often.
I belong to a small rural "redneck club" about 15 miles from my house. They have a 70' indoor range. Any conventional pistol can shoot there, no rifles other than rim fire. As the club is small me and Mrs Lakesider go there about twice a week lately and have always had the 9 position range to ourselves. Its heated and a heck of a lot better during the winters or rain time of upper NYS.
FWIW the club also has up to a 200 yard outdoor range
