From my personal experience, liquids that are high in PG taste awful.
They do have a very strong throat hit, but that's definitely not a selling point for me.
Keep in mind, though, liquids that are high in VG are much thicker and harder to wick. You may experience dry hits if your
device can't handle the thicker fluid. IMHO, 50/50 blends are a good place to start. From there, you can experiment with different blends and see which you prefer.
