Hey Kuwarpal, Thats a very broader kind of question to answer as both the places have their own uniqueness reserved for a traveler ... Paris is a city with lots of harming all over and USA is a big big country Bro ... If you can reframe your question it would be better ... I would say both are worth a visit ... If you have heavy wallet with you visit both the places Bro .. Happy Travelling !!!
Paris, every time. Although I wouldn't recommend going there now. There are protests going on Paris regarding hike of fuel price and it has turned pretty violent.
From these two countries both are very interested. But in here I would like to suggest USA. There are lot of places such as Florida, Francisco, Los Angeles etc.
San Francisco is the most visited city in the whole country and the crown gem of the north because to its numerous famous and highly regarded tourist attractions. This city is rich with famous and historical locations, including museums, parks, beaches, and wonderful neighborhoods, among many other things for your enjoyment. The most well-known locations with spectacular sight views are Alcatraz Island and Fisherman's Wharf. The largest Chinatown in the northern portion of the country is also located in this city, and it is well worth a visit. The cable car journey is one of the greatest things to do in the city, in addition to other things.
