Alright so from experience, Yamaha are usually reaaaally good. It may not seem like it but their mid range guitars are really amazing. That being said, I took a look at the package you are looking at and checked the specs. Technically speaking, you get more with the Yamaha kit as it comes with amp and accessories. The schecter SGR series just come with a gigbag if memory serves right. So in terms of value of content, Yamaha.
Now, which one would be the best? Honestly, we are talking here about entry level guitars so the quality will more often than not be a gamble. They will be fine either way because in the end their purpose is to get you started you know? Both seem to be made in china, they use the usual woods for these level of instrument. But if I'd have to chose the guitars solely on specs, I would go with the schecter.
However as Ids mentionned, it has a Floyd Rose. And seeing as its an entry level guitar, chances are that its going to be unstable and floyd rose are difficult to adjust if you dont know what you are doing. It's not impossible but its definitely something you need to be aware of. Adding to the fact that Floyds will lock your tuninng so that is definitely something I would take into consideration.
So in conclusion, if you are just picking up guitar for the first time, I would go for the Yamaha kit. The Schecter has risks to frustrate you very fast with the floating bridge. And as mentionned, if you are a beginner the truth is, you will not really feel or see the difference of quality. Picking up a guitar and having a feel for it and knowing if its gonna be good or bad (for you) requires a certain level of experience. Knowing yourself as a guitar player and what you want/need or what you don't like, etc. And im saying that as someone who tried a lot of guitars including high level custom shop and just didnt feel for them. And yet eventually someone comes, tries it and its the perfect guitar for them!
However, if you already have an electric guitar and this would be your second one, I would suggest to skip them as they are not much of an upgrade and save up for something better! I hope I help and I wish you good luck in your search!
