[What Bike]: Which bike to go for yamaha R15 or Fz-s ?

So here it goes . My first post in xbhp :):):). i am going to sell my Honda Shine for Rs. 40,000. and Buy a bike in 2nd Hand . ( buy a used bike . second hand).

My Main options are Yamaha R 15 or Yamaha Fz-s or Pulsar 220 ( jus p220 fr a feedback).

My height is 6 feet ( im slim) and mostly am going to use it for 3 years for city ride .

the usage is simple just ride for college travel and hangout places in city . but for that i want a beast with killer looks and no top speed or racing stuff just a showoff and speedy one ( just speedy not fastest ) .

The main thing is after buying a moderately used one in second's (whichever from above options)

i am going to modify the bike to extreme level i.e.

1) by painting it to a different black and gold color .

2) By putting double exhaust system and modified green led head light .

so the mileage is not at all a concern to me .

Again its just for my solo riding purpose for college and hangouts . and am gonna do the modifications that i mentioned above .

so which one exactly will suit me to my needs ? please suggest me with a good choice .

kindly excuse if any silly questions because its my first post . :):)
