Having lived in / visited a few dozen cities in Europe, I actually think trams are generally preferable to subways. In places with both, I tend to use the trams almost exclusively.
A hop on, hop off tram system is much quicker and efficient than going into a subway station, then back up, etc. At least if you aren’t going entirely across town.
What makes for a more pleasant experience is not necessarily the optimal choice for commuters as subway wins over trams by close to an order of magnitude in terms of throughput.
In the city I grew up in during rush hour subway trains leave less than every two and a half minutes and pack well over a thousand commuters each. That is an impossible feat for even the best tram system, as they're limited both in vehicle and station length, not to mention speed, as you can't have 40 tonnes of metal hurtling at 80km/h through intersections.
And also they have much less capacity than mass transit systems like a subway, so they are bad for most commuters who tend to travel at rush hour[1]. I guess they are great in tourist areas though.

You could argue trams are more romantic. That is probably the major advantage.
I'd argue there are some limited places where classical trams on the road make sense, like some down town district. But you get almost the same utility with busses, passenger flow per lane is lower with busses, for a lot less money.
If I’m going one, maybe two stops, a tram can be optimal if it’s already in front of me[1]. Otherwise the subway tends to win the curb to curb speed contest for me. It’s a little more traversing through the subway’s infrastructure and getting to the right platform and the right part of the platform, but I’ll get to my destination in less time and it’s not even close.
[1] Otherwise I have to check the Transit app on my phone and do some math factoring in the wait time and the time it takes me to get to the platform. The subway usually wins this contest too.
Depends on the city, but in most places the lanes are wide enough that a tram-designated area isn’t really an issue. Even then, it wouldn’t be a horrible idea if an avenue (running north-south) or two in Manhattan had one less lane for cars and one more for trams.
Not necessarily. Unless I am misunderstanding what specifically is being referred to as a tram. In Portland, Oregon for example, we have small trains that run at street level and share lanes with automobile traffic.
Portland's trams don't move anywhere close to 35mph as the OP mentioned. Portland's trams are quite capacity constrained due to needing to navigate the short blocks and many intersections of downtown Portland. Dedicated travel cooridors where these trams could move at closer to 35mph would allow trips _through_ downtown to become competitive which currently are often not ideal.
