Same experience for me. I've got a 4G dongle that I use for travelling and it's both faster and more reliable than my home broadband connection (no fiber available in my area). Just keeping an eye out for a cheap 4G data SIM so I can switch to the dongle full time.
Recent EU roaming regs are also a boon, buy a data SIM in your country of residence and get coverage across the EU at no extra cost!
