GPS tech (Garmin, Hammerhead, Wahoo, RWGPS, etc)

My comically old 705 has died, again, and this time I’ve decided to let it go to the big gps party in the sky. Must be more than 15 years I’ve had it.

Anyway. Recommendations please.

• mainly used for realtime data while cycling: power, time, etc.
  
• need route navigation: upload a GPX or whatever and then turn by turn please, with reasonable off road (bridleway type stuff) routing
  
• must be able to press intervals start stop (worst case in thick gloves in the rain)
  
• Painless uploading of rides
  
  

That’s about it really. What’s the cheapest best option?
