The Exclusively EVA spacesuits are getting more and more complex (and heavy, but in weightlessness it doesn't matter, it might matter on the Moon and more so on Mars).

Those spacesuits must last a long time, be carried for hours and hours and frequently.....This is why hard parts become more obvious.
Those spacesuits include life support systems for, say, 12 hours, food, water.
They include lamps, TV cameras, computers with screens, all kinds of tools to work with, sample bags.
They must sustain vacuum, extreme temperatures, micrometeorites, solar radiations, sunlight and have gloves swift enough to use them for work and for hours and hours...

None of that is necessary for pressure suits.
