For the level of your question, spending 2 stacks plus on the X would be a mistake. It would frankly be a poor investment, especially with the dirth of Live's that can be had at a good cost these days. You use the X if its going to be a centerpiece of your studio, and thus needs multiple inputs (your question makes it sound like you don't have a bunch of outboard gear, and thus don't need this). You use the X if you want/need buttons that avoid menu diving or want to avoid holding shift to access secondary options. I've honestly heard both sides to the arguments on that alone as a Live user still contemplating getting a X myself, I keep my ear up, and surface level, you aren't saving time with the extra buttons. The Q-Links are a definite plus, though muscle memory from use will reduce the gap of having 4 vs having 16.
Going the other way, the Live is portable and has all the same functionality, with fewer I/O. The screen is smaller, but how much that matters is a valid question as muscle memory with Q-Links paired with the lack of need of "perfect interaction with touch screen". Tilt isn't really an issue, if you want to tilt the Live, you can grab a laptop stand for 7 USD that will suffice from Amazon (I have this one I grabbed for that price on sale

I'd feel different if the X was substantially cheaper, but the currest cost in USD is WAY too high for starting out on without prior experience, heck at that point I might even just get something like the MPC Studio and run it off the MPC software until I felt the proper pull to the X or the Live. I jumped to Live because being able to use it at work means I'll actually get time away from my kids to work on music (during lunch), and I'm only feeling the urge for the X as I've started to prefer making music on the Akai platforms (ironically I felt the tug the other way back to Ableton, so I'm just waiting, give it a year or two to see what's next in the standalone landscape).
