As availability of spare parts will eventually become an issue, I'd be inclined to favour the FE2. There are far more of them around than OM4Ti's (at least here in the UK) It also wins out on the grounds of "the simpler the electronics, the less likely it is to fail". I've used FE2's, FM2's for years, they handle well, are solidly made to last a photographic lifetime.

Also, do you really need to take eight different spotmeter readings before exposing?...By the time you've done this, the picture opportunity is likely to have disappeared.....the sun's gone behind a cloud etc. etc. .....In my experience, in day to day photography, these complicated metering systems just don't get used.
