I think live weather is improving quite a lot.
Meteoblue website is now displaying METAR and TAF data. For example: Current weather Liverpool Airport - meteoblue
They didn’t show all that in the past. I know because I browse that site almost every day and before each flight for MSFS flight planning.
Earlier in the morning I spawned at EGGP with live weather and the in-sim weather matched letter by letter, word by word, with the then METAR published in their site.
