In a 'general sense' MGM-Mirage has treated their mid-level table players better than Harrah's (Caesars).

Per a report at VegasTripping (which seems to have disappeared), it seems that host interaction (and discretion) with regard to table players will be quite similar; even though Mlife is live. Things like express-comps accumulation are reported to be disappointing, for strictly table players (but, once again, most of the 'comping' will still be handled by the hosts, per the report).

Unfortunately, I can't speak personally, with regard to table play @ MGM-Mirage; as I seldom play at their properties.

My suggestion, would be to get a host recommendation from the property you desire to play at (in the MGM-Mirage family); and describe your play (action) to the host; asking what you can expect.
