MTQ Capture is by far the best imo.

She tells you the ins and outs of a fight with a pleasant demeanor and some fun little witticisms so I would just stick with hers for your main guide. I haven't found other guides that are nearly as appealing to listen too nor do they give anything new and I tend to avoid Happy at all costs as I find his videos and personality quite grinding.
Not to diss mrhappy but sometimes he hits you with a wall of just speech and goes on and on so it's hard for me to understand what's going on and MTQ Capture most of the times has diagrams with her videos so it's easier to visualize. I see Xeno's channel but doesn't seem to have guides on his youtube does he have a personal site where he posts stuff?
