Why are you looking to upgrade? Are you chasing detail, speed, or something else?

Detail. I'm looking to achieve tighter tolerances with 3D printing, going for dimensional accuracy.
Dimensional accuracy doesn't necessarily mean detail. What are your expectations? You should be able to get fairly crisp and dimensionally accurate prints, but there's a ceiling. With FDM you're ultimately running what could be considered a CNC hot glue gun so absolute accuracy won't ever be as good as a resin or SLS printer.
Do your parts look good, but their dimensions are off? If yes, you probably need to scale your parts to accomodate for shrinkage. That's what the Voron team did and their parts fit together really nicely with non-printed parts when printed on a decently tuned printer. Their threaded test prints are a pretty good indication of how well dialed in your printer is.
Some of this also comes down to temp and material, so if you had the perfect interface and changed material you might need to iterate a few times. There are also the design quirks that you learn as you go, especially for things like small holes in parts often being smaller printed than designed. Print a hole gauge set, with a series of holes ranging in size, and use the one whose printed - not designed - dimensions are the one you want.
You are literally the first person that I have heard about who is satisfied with a microswiss hotend. Most people say it is overpriced and not very good compared to others (like the Dragon hotend)
Hmm. I bought it a few years ago when there weren't many all metal hotends. It's never caused any issues.
Back then it cost me about 80 euros which was a bit steep but acceptable.
Back then my reasoning was that I didn't want any PTFE close to the hotend, fearing offgassing and limiting my options for filament types.
Don't know where you heard that but micro Swiss hotend has been really popular until dragon hotend came out. I'm not saying it is better than dragon but was known to work great. About prices, it might depend where you live as I just checked right now and dragon is more expensive than micro Swiss.
Nope, it is not significant. The only thing that really stands out is the runout sensor with loading function function that is sold for 2.0, if you dont need that, print ninjaflex 24/7 and your 1.5 has no direct issues there is no need to upgrade.
What about the filament feed path? I have a 1.5 and the only thing about it is that I have to hand feed filament changed because of the space in the path between the gear and the bottom going towards the hotend
Before doing anything extruder related watch this. This guy went way overboard so we don't have to.
Don't know which printer you have but if your main interest is a direct drive setup over Bowden, chances are that you can setup your orbiter 1.5 as direct drive by printing some adapter.
The orbiter 1.5 is already a DD design
Oh, then I guess I didn't understand OP correctly as I understood he has a Bowden setup with his orbiter. Thanks
