OK I've played both games quite a bit and have drawn some conclusion
1)Yu-Gi-Oh! is far more expensive to build a competitive deck for, this is one point where Magic wins out totally, the most expensive card in standard has just gone and was ~$100 at peak, which compared to Yu-Gi-Oh! is normal (DAD?, Judgement Dragon)
2)Yu-Gi-Oh is swingier, you can create lethel damage from an empty board with ease and doen't have the summoning sickness rule to slow OTK's down
3)Yu-Gi-Oh rule mechanics are awful seriously they're a mess,look up missing the timing on yugioh wikia if you want to see the awfulness, magic on the other hand has nice clean rules boxes, with proper guidelines on how what is a cost and what is an effect(Also sadly lacking in yugioh).
4)Magic finds room for flavour text in a large amount of its cards, its a minor point but still.
5)Drafting- Magic is designed so that 90% of its cards are usable in some way for a format called limited(Take a number of boosters and make a deck) unlike Yu-Gi-Oh, which has so much chaff its unreal
6)Yu-Gi-Oh generally makes better crafted archtypes,based around cards with certain names(E.G. Elemental Hero -) It a cute way of doing things and lets you design unique playstyles for a deck(Although since its translated from Japanease things can be amusing E.g.There's a archtype called "Archfiend" and "Summoned skull" is one of them, because he's named as an "Archfiend" in Japanease, could you imagine trying to explain that to someone who didn't know that?
As for ease of Learning-Magic is slightly more difficult to get to grips with, but really if you can't understand it, I worry for you, but once you learn the basic rules, the cards explain themselves perfectly and you don't need rules knowledge to know how they interact nearly as much as in Yugioh
TL
R/Magic is the superior game.
