Personally I would use the best available tool I have for any job, consistent with being able to use alternatives if necessary.
Agreed. FWIW I use a G296, flying around the Czech Republic, Germany, Poland etc (for info as OP said he plans flying around Europe), and have no complaints. Very clear in the 172 cockpit and the perspex of the Zlin 142. And yes, I do use it as primary navaid when going somewhere unfamiliar, particularly if using controlled airspace. I also use VOR, NDB etc as backup for enroute and stopwatch and line on a map as a final line of defence.
My challenge is remembering to make sure I keep using the map/stopwatch on a regular basis as primary nav, since the skill does decay ever so fast if you don't use it!
