Yes - I have a Phillips. Love it; use it every day.
Same here, I have the Phillips 5400 LatteGo and love it. I use it every day (except Shabbos) for at least 3 - 4 cups/day. Yes the price is steep, I got it for a few hundred off retail after factoring in coupons, cash back, etc, but it was still very expensive (around $700). I do not regret my decision and am happy with the 5400 over the 4300 & 3200. Some features I thought I'd use from the 5400 I don't use at all but overall am still happy I went with the 5400.
As far as "taste" I cannot give an accurate review since
a) I have nothing else to compare too, the machine I had before was a standard Cuisinart drip coffee maker that was 15+ years old.
b) I like my coffee sweet and lots of cream so I typically add flavored creamer to it, or sugar.
