There will definitely be comparison reviews between the two but since there are no more brand new 1Ms the test specimen must be chosen carefully in order to make it as apples to apples as possible. I hope they pay attention to one detail: that 1M also wears Michelin PSS in stock sizes. Lots of them already finished the factory PS2 sets and naturally passed to PSS.
Otherwise, some things seem easy to predict: a 8 speed auto will be equally fast on straight line acceleration, manual I don't think so. Seems that M135i does sound better in stock form. It is the more practical choice but if it is a 2 door not by too much. Better plastic quality, more modern layout of controls, more options to choose from are all facts. Better ride quality too. Overall a very good car with some advantages over 1M. And this before you factor it to price.
On the 1M side, it is for sure the quicker car around curves and race tracks. It has more power and torque (all 1Ms are minimum 350-360 ps and 550+ nm, never heard any less). But it is also heavier than M135i. It is the simpler, more straightforward car for enthusiasts. More visceral maybe. Manual to manual I doubt M135i box can be better than the 1M's, it seems that they worked heavily on the 8 speed auto for this car. Ultimately brakes should be better with the 1M as well as the steering feel and response.
I think one is really the little M car and the other is versatile M Performance car, for anyone who don't care about these differences then M135i is definitely the right car, especially with that price difference! And yes bang for buck the newer car offers more but it also is not as special as 1M, it will be all around the globe (sorry NA guys) in big numbers and it just doesn't have the aggressive and headturning looks of a 1M (especially so in VO).
These are my educated guesses at best but I would love to read a balanced review with a real road test about these two from someone that knows what he is talking about and not trying to highlight one over the other, wouldn't be fair for both cars. They are the best BMW offered in recent years and I like that they are quite different from each other if you take into account what they focus on.
