G1 you can argue for with the changes in the JDK, though it's MUCH less friendly to small heaps (e.g. probably our default simple user).
Offheap memtables are different though. If someone wants to attest that offheap_objects get the same level of rigorous testing as the existing default, that'd be useful, but I'm pretty sure that's not true, and bugs like https://issues.apache.org/jira/browse/CASSANDRA-12125 (which remains undiagnosed) reinforce that it's less commonly used and may have latent undiscovered bugs for default users.
