In Daggerfall, Battlemage presets are very similar to Arena as far as their limitations go. So, clearly, Spellswords are tankier and tend to have the most HP of the mages, but a Battlemage will be slinging spells more often and spending less on making them. Spellswords can wear up to chain (medium) armor and any shield but tower shields, have 1.5*Int spell points, and have 25+d12*level HP. Battlemages can only wear up to leather (light) armor and up to round shields, have 1.75*Int spell points, 25+d10*lvl HP, and damaging spell effects are cheaper to make in the spellmaker. In Arena, Battlemages and Spellswords are both considered "Mage" classes.

Because there is a difference and it depends on the game.
