depending on how you intend to train, I find these sites to be very good for gaging good practice weapons most of which are quite historically accurate without sacrificing durability to make them as such.

if your intending to do contact training a sword that can strike a tire 2k times and still be solid as a rock is a good practice sword in my book, however they are not always balanced right(the first site adds this into its ratings so read up on them) tho many are fairly historically accurate.
I know quite a few people would spending a fortune on Albion or the like and then not what to practice with them for fear of scuffing your 700-1000$ sword.
for practice weapons Generation 2, Darksword, or Hanwei are going to be your best bets.
Darksword has the best durability however gen 2 will actually replace a broken sword 1 time along with being extremely durable in the first place.
if you plan on getting a gen 2 sword i suggest getting one from www.armsofvalor.com as the discount code SBG will get you a discount on them of 10% off
I know my fist statement might sounds bad however truly historically actuate swords will never hold up against Direct blade on blade contact for long as it leaves huge rents in the blade which is why I like these lower priced but more durable swords for practice as you don't feel bad when you happen to mar them which does not happen easily I assure you, and they give you huge amounts of leeway to screw up any number of times if you are practicing sword on sword contact.
