As mentioned, I would wait to see what actually happens. Some differences are shown only at benchmarks and at very heavy use during artificially high stress situations, not during everyday regular use. And if you really, REALLY have these high stress performance requirements, it’s a good reason to prefer the chip that can offer you the slight edge.

I agree a good standard of the same chip should be set, but this is also a practice by their major competitor (Apple where a very slightly weaker chip is placed in their "regular’ iPhones). Honestly it’s not anywhere near as much of a deal breaker as the web’s herd mentality thinks it is.

“We gave Samsung 3 shots to prove themselves with the exynos chips and all 3 times they failed. I don’t have high hopes for another exynos coming. Even if it has good performance then what about battery efficiency? Cameras? Heat optimization…etc etc.”

Battery efficiency might be slightly (SLIGHTLY) better with Snapdragon but we don’t know that yet. Cameras in terms of hardware are completely independent. In terms of processing, I don’t expect any major difference as the more CPU-demanding tasks will be needed only in the case of the top model (the Ultra). Heat optimization is partly associated with the power consumption of the chip itself and partly with the cooling design of the board which will probably be identical between the same models that will have Exynos or Snapdragon. Again, we will only know when the dust settles.
