One way to look at this is to ask yourself what kind of brewer you are
(or think you are) in terms of how hands-on do you want to be when
brewing.
If you like to be involved in every stage of the whole brewing process
(and this will be for every brew you make so ti can wear a bit thin after
a while), then 3V (or non-BM) would be the way to go.
OTOH, if you like things to run themselves and a much lower amount
of things you have to do each time, then the BM is the go.
This is true whether you buy off the shelf (like the BM, or even a 3V)
or if you can tinker and build it yourself (including building a BM style
design like those already done on this forum) then you can fix things
if they go wrong.
