Depends on the level of pain you want.

12.3 mainline has features that 12.2S does not have (VPDN, for example).

12.2S "provider" has features that 12.3 main does not have (IPv6 and MPLS,
without having to pay $LOTS extra for 12.3 "enterprise" feature set).

12.3T has features that neither 12.2S nor 12.3 main has - but it has many
more bugs, and needs more Flash and DRAM space.

So... it very much depends on what you want to do

  - if you need 12.3T features, go with 12.3T
  - if you don't need MPLS, 12.3 main might be a good path for you
  - if you don't need IPv6, 12.0S might be a good path for you

Our choice is 12.2(18)S10 for the core routers, and 12.3(x) mainline for
the VPDN aggregation routers (and due to feature availability, also for
a few other customer-facing boxes).
