The transition era was certainly annoying, but now that it's over I think the Mac experience is objectively worse. My PC laptop has 2 USB-C ports that can be used for charging, display, 40 Gbps transfer, etc., just like my Macbook Air. The difference is that the PC also has 2 USB-A ports and an HDMI port. This means that I'm able to plug in a flash drive or connect an external display without having to remember to bring a dongle with me.
I largely agree that PCs have caught up feature-wise, but because they took longer to get there, I still have a couple crappy USB-C ports on PCs that are otherwise fine.
The problem with the 2 USB-C ports on modern PC laptops is that one of them pretty much has to be reserved for the charger, whereas the MBP has a MagSafe port that you can charge with instead. So it really only feels like you have one USB-C port and the other ports are just there as a consolation. That might work out to roughly equal, but I don't think it leaves the Mac off worse. I don't hate the dongles so much though.
It wouldn't have hurt to have some USB-A and HDMI on the MBP--the Minis can pull it off, so clearly the hardware is capable--but more (Thunderbolt) USB-C would still be the best option IMO. USB-A (definitely) and HDMI (probably) will eventually be relics someday, even if they are here for a little while longer.
The current Macbook Pro design also includes an HDMI port.
Can those USB-C ports charge your battery if it is completely empty?
Yes, they're the only charging ports on the laptop.
