Looking at bringing one of these Oldbloods to an upcoming tournament - any thoughts on which is the best all-comers?

They all seem pretty similar. Without knowing what unit he's going to be joining and not knowing your opponents I'd go with the one with Sword of Anti-Heroes. I tend to get schooled most often by character heavy armies.

If your mounted Saurus is going to be in an infantry block and facing cannon users I'd suggest giving him a build with a ward save.

I don't normally use the Crown of Command myself because I tend to put my Old Bloods in Temple Guard blocks or very deep ranked Saurus blocks.

My personal favorite is Fencer's Blades plus Glittering Scales. I like to try to avoid being hit in the first place. When someone does step up to the plate to fight an Oldblood they are usually hitting at S6 or better which will knock your armor save down when you need it most.
