Hi!
I stand between buying or building a guitar multi effect pedal. I want to know the pros. and the cons. with the two options. Which one sounds better, what is the cheapest option and so on.
If building my own is a better option, what is the best instruction?
Unless you are a very experienced engineer who works with DSP for musical instruments then it is a sure bet that the one you buy will sound better.
Unless you're planning to build them in huge quantities so you can get volume discounts on parts then the one you buy is going to be cheaper by far.
The only reason to try to build your own would be for purely educational purposes. It will take a long long time to complete, will cost a lot more money, and most likely won't sound nearly as good.

Or unless you are Eddie Van Halen. I think he built a lot of his own equipment.
Lots of guys did back then. But they used a different kind of gear. Digital signal processors are a much trickier thing to build and program than a tube amp or an analog delay box or a wah pedal. Any numbskull with a soldering iron can build a crybaby.
I'm not saying it wouldn't be an interesting project. I'm just saying don't build it because you think it's going to be cheaper for sure. It might be a really interesting project to build an old-school analog delay box and a wah and some stuff like that but use digi-pots instead of knobs and stuff so you could control it all from Arduino. It would be a big project but if you're really into learning a whole bunch about it and don't mind spending money it could be really cool. I used to get into old school synthesizer stuff back in the days before computers did it all. That stuff was a lot of fun and it is cool to know how it actually works.
Yeah, I'm not saying that it can't be done or that it wouldn't be fun to try. I'm just saying don't think it's going to be cheap or easy or sound good the first time. Even Eddie had to screw it up a bunch before he got to his sound.
