I have Tom Tom Go from Tesco's as they were doing a deal c £80 last Xmas .
The only issue is the cost of maps etc. plus it has speed cameras on it which you must turn off in France.
I still have a c 8 year old one from a defunct comapany and in truth the maps are still good enough even if I never updated them.
Many models now have free lifetime map updates. Annoying as I still have to pay for mine

All recent or updated TomToms have French speed cameras replaced by accident risk zones where speed cameras may exist but are not specifically localised.
A major defect of the current TT series is the limited number of waypoints and the total lack of itinerary planning. This is only a problem for long distance travellers and delivery drivers, but annoying as the previous series included decent itinerary planning.
