whereas in Erlang (IIRC) ETS cause some issues with GC
There isn't any at all for ETS:
Note that there is no automatic garbage collection for
tables. Even if there are no references to a table from
any process, it will not automatically be destroyed
unless the owner process terminates. It can be destroyed
explicitly by using delete/1. The default owner is the
process that created the table. Table ownership can be
transferred at process termination by using the heir
option or explicitly by calling give_away/3.
Of course, you'll seldom be using ETS directly, but rather through Mnesia.
