I think the Asian trip would be a better option to go for because these places are cheaper than India and also u can cover more than 1 country in the total amount which u will put in European trip.
Depends on which season you are planning If summers , then go to Europe For other season like if you want to go immediately or in Oct to dec then these Asian countries are the best
Both the options have their own charm - an Asian trip will show you a cultural diversity in tropical chaotic conditions, while a European trip will give you a glimpse of a very organized and well kept world. Also, budget should also be a consideration. Europe trip would be a bit more expensive.
Hey this time totally depends in what your interests and likings are and also your budget. South East Asia is very beautiful and budget friendly. Europe is mesmerising and has stunning landscapes but it's costwise higher than southeast Asian countries but worth the money spent! it's upto you ultimately to decide what suits you.
Certainly a European trip to Prague,Berlin and Amsterdam.
Prague is the cheapest of the 3 cities.Amsterdam is also small but beautiful.
In total it would require a maximum of 6-7 days for you to cover the 3 cities.
