They sort of do different things. Spell Siphon is an overall change to how magic is handled allowing you to switch spells on the fly to build up combos and let you get away without using magicka via clever play. Mage VR is just draw symbol in air with trigger to switch to or cast a spell. Spellsiphon genuinely makes combat interesting on top of allowing you to not touch menus as a mage which is why it is so highly recommended. It doesn't use a trillion buttons either, just the shout/cast button thanks to the draw and focus system it uses. The mod's page explains it better than I do https://www.nexusmods.com/skyrimspecialedition/mods/26627

MageVR does add immersive lockpicking and backpacks, but honestly neither feature works that well. The backpack is just a list that is clumsy to scroll through. Compare that to the grid based system that Saints & Sinners and Bean Stalker have which are actually intuitive to use. Or better yet Into the Radius's spatial backpack. The immersive lockpicking just adds a new minigame that spawns a cutout of a lock in your hand that is just Oblivion's lockpicking minigame. It is genuinely more annoying than Skyrim's normal lockpicking, but I may have just been filtered. MageVR's own holster system is done better by VRIK. All in all it has cool ideas but I don't see a point personally.
