Hi

I expect you'll get a variety of answers to this one and it's down to personal preference and your own country of origin a lot of the time. Some of our friends down under swear by Lithgows for some unknown reason!

Personally, out of my own 10 SMLEs, the best for quality, fit of wood and finish is probably my 1905 BSA rifle, with my 1914 Enfield a close 2nd. Later in WW1 the quality of wood dropped off and you can see the differences.

Commercial rifles (BSA and LSA) are generally made to a high standard and not under the pressures of wartime production.

You may wish to choose a more scarce manufacturer (e.g LSA Co.) or a WW1 'peddled rifle' (SSA or NRF marked), but they won't necessarily shoot any better or worse than any other IMHO.
