mobil 1 no questions asked
Both are excellent oils. This will turn into nothing more than a popularity contest so Mobil 1 will win by a landslide. In your engine? Highly debatable, so it comes down to what you've liked best. Have you noticed any differences so as to develop a preference or run any UOA's?
Syntec is about as popular on this site as herpes.
I've used Syntec in the past, and have some stashed that I'll use in something at some point, but between the two brands, I'd select M1 0W-20 over Syntec 5W-20.
There are solid UOAs in that forum with the M1, not so much with Syntec.

Your "sources"? Dude, your information couldn't stand on its own if you bought it legs.
Newsflash: Mercedes, Porsche, Audi, GM, Honda as well as the SRT line from Chrysler all use Mobil 1. They all work with ExxonMobil to develop lubricants and they all perform EXTENSIVE testing with Mobil lubricants for durability, performance and the ability to protect at the extremes.
You have no way to ever, EVER test a lubricant as completely as these folks do.
Doug Hillary put MILLIONS of Km's on Delvac 1 at extended drain intervals and even provided tear down pictures of its performance in high stress OTR diesel applications.
BMW has a working relationship with Castrol. But I run Mobil 1 0w40 in my M5. Why? Because:
A) Doug told me to, and I hold Doug's opinion in the highest regard.
B) It meets the specifications for my car (BMW LL-01)
C) I've had 15 years of experience with Mobil 1 in a wide array of applications and it has always provided me with a clean, wear-free engine, no matter how had it was beat on. This includes a 425HP Ford Y-Block in a 1931 Chris-Craft.
-You have no data.
-You have no facts.
You have anecdotes and bias, which you express in a manner that is far from anything anybody would consider "convincing".

Both oils will do just fine, buy the least expensive oil.
i like mobil 1, and ive only used castrol a couple times. it was gtx and it seemed good, i like that it got dark quick,it at least made me think it cleaned well. who knows. but the new edge with titanium interests me. ive been impressed with mobil's super line that uses titanium. id say both will serve you well. most will prefer M1. Ive had good luck with M1, i however do not have any doubts that castrol syntec or Edge aren't just as good.

I`ve always wondered how M1 15W50 compares to Syntec 5W50.

You mean "drop the ball" as in having the largest market share of full synthetic oils and being the #1 selling synthetic on the market... I'd say touchdown.
