We don't yet have a thread here at the Oneworld board where one can compare/contrast various member FFPs, so in the interim I'd encourage members to research the various plans in contention using the resources available on FT, in particular the various airline-specific forums.

One thing to note, however, is that BA is quite stringent on enforcing the rule that each status tier requires four BA-metal flights, which might be an issue with your travel pattern.
