Hello,
I have an E-M5 from more than a year, I'm not a pro.
I don't own 43 lenses but only some native micro43 lenses, but I was considering to upgrade to E-M1 mainly in order to get some advantage from the PDAF in continuos AF, wich I found to be the only limit I have in the camera when I try to shoot to my erratic running 4 y.o. son.
Yesterday there was an Olympus event in my city and I have the possibility to try the E-M1 compared with my E-M5, indoor and outdoor. I have tried it with 75/1.8 and the 12-40. On my camera there was my 75/1.8.
Now, before being bashed, let at least me clarify my points, which obviously are subjective:
The E-M1 is a great camera indeed, actually it is the flagship of the m43 arena, well built/sealed and full packed of features. The IQ level is very good as we already know. If you have no budget limit and you get one you cannot go wrong.
The E-M1 is an improved camera under a lot of aspect in comparison to the E-M5, as it should be being more recent and more expensive. I don't want to list all here, but you get an idea: the EVF is bigger/better, the IBIS is improved, the LCD has more resolution, there are more external command and it has the integrated grip, it is more fast with a bigger buffer.
However the IQ is very similar if not equal, the jpeg are better processed/corrected but if you shoot RAW (as I do) this, and all the art filters, are way less important.
That said, I asked myself, main improvement aside being already listed above, for my type of shooting (no 43 lenses, no manual AF, no pro work, RAW only, very little videos), what exactly I can do with the E-M1 that I "cannot" do with the E-M5?
(I'm focusing here on what is impossible/absent, not on what is improved, like the EVF for example).
My answer was:
- PDAF (hybrid C-AF tracking, up to 6fps)
- 1/8000 shutter speed (useful in bright condition, maybe in conjunction with ISO LOW)
- 1/320 flash sync
- focus peaking
- WiFi
- timelapse
- HDR
- micro AF lens adjustment
Yes, maybe I'm missing something and you could add other items to the list, but these are the main I have found, and in addition the only features which are of my "real" interest are only the first three.
Knowing that, I was curious to test the hybrid PDAF+Contrast AF in Continuous/tracking yesterday, being a main reason to consider the upgrade, and frankly, after some test, my conclusion was that this aspect was improved but not so much or, at least, not as I hoped for.
In addition I was not super impressed by the new EVF as other were, neither found the overall feeling/layout of the commands being so decisive. I have the grip on my E-M5 and the E-M1 is similar to an E-M5 with the hand grip only, but I find more effective to have a modular approach, that allows me to put a very slim lens on the bare body and get a small package, which you cannot do with the E-M1, being the grip fixed.
So, my final thoughts after my test, considering all the improvements and including the C-AF tracking comparison, was that in my humble opinion, for what I do, the current big price difference between the E-M1 and E-M5 is not worth what I get in exchange.
Again, this is very personal and based on my requirements, so please, don't flame me.
In my opinion, if your requirements are not specifically and strongly toward what unique/improved the E-M1 has to offer (including the fact of owning some old 43 lenses obviously), and you are budget conscious, I think that the price difference is better spent buying a lens.
In addition, due to the fact you explicitly mention "long exposure shooting", I want to highlights that in long exposure shooting, if you disengage the black frame noise reduction subtraction (as is required for star trails, for example) the E-M1 is surprisingly noticeably worst than the E-M5, as you can see by looking at this thread:

So,
I suggest you to make your own consideration and, if possible, to try both the camera before deciding,
I hope my experience/opinions could be useful for you in some way.
Keep in mind that, based on what I have written, I will keep my E-M5, but if someone gift me an E-M1 I will not cry for sure...!
Ciao
