Whether the UI changes are worse is a subjective claim, but the data Google has has not gotten worse. I've found all the alternative mapping solutions (Here, Bing, OpenStreet, and Apple maps) to be inferior when it comes to data quality which is the more important factor, unless you think getting directed through non-existing streets is a small concern. I'm not a Google fan, I've given up a lot of Google, but I can't quit maps or google search, although I use ddg quite a bit. Google has the most reliable map data, there is no competition and no good alternative.
Unfortunately the US is not yet (consistently) one of those countries. But "there is no competition and no good alternative" is an over-generalisation.
About two weeks ago I was unable to switch to Street View in the android app. It simply wasn't accessible through dropping the pin, as it was in the past.
When Google's flagship app on their own platform forces me to find computer and use the web version, something is seriously wrong.
The first thing you should have seen after updating and adding an address is a message telling you to pull up to get more detail. It took me 2 seconds to figure out how to get street view in the new UI. So as I said subjective.
Two weeks ago, it didn't. I even googled it, how I'm supposed to find it. The street view strip just wasn't there.
It's unpredictable. Nothing subjective, just seek-and-hide UI, which was always hallmark of bad UI.
It'll just take one half-decent app or company to take me away. Maybe HERE is the one. I will try it.
