If home is EU go for EASA
If home is in EU get an EASA unless you plan to stay forever in CA. Atleast every 2 year you won't need to head to CA for renewal and conversions won't give żou a headache. Before heading to CA, use the Foreign License Validation Form to be able to fly and log your time there. Eastern EU gives PPL at 6-7k EUR(schools with good reputation, eg: Pan Aero in Croatia). Never ever forget aviation is a money pit, you're never guaranteed you'll make it through the minimums. You could be making it to your PPL in 1 month under the bare minimums in that side of the world. If you want better, airclubs in France are also proposing intensive ppl training for 8k EUR in summer.
