Up to you and how you play I guess, but if you want extra health and stamina then you are better off using tri-glyphs on armour before changing your skill points (if you don't mind spending a little gold).
Unless things have changed this would give you 50% H/M/S vs. 100% of just one stat. For example a tri-glyph on a large piece would give 434 Stam, 434 Magic & 477 Health, rather than a single resource glyph of 868 for Magic, with no increase to S or H.
Hope that makes sense
