I think it depends on if a person is just meandering or rushing.
If we meander, we come down via Bergerac, Marmande and the direct road (D933 from memory) to Mont de Marsan and on to Dax. This is not a diversion costing lots of extra miles and is a very scenic route.
Bayone is a pain and even if we come via Mont de Marsan, we usually jump onto the Autoroute near to Dax to Irun, and then immediately after the border, turn up the N121a to Pampalona
Lots of alternative routes before Bordeaux or even from Calais. I could go on and on regarding their respective merits. But the OP and others were specifically enquiring about the R10/A63 toll charge, and associated issues.
