Slice Cards and Savings account

Hi, I opened the slice savings account and got approved for their credit card. my limit is 1 Lakh and i was quite disappointed thinking it could've been more but when i saw most people here having a limit of 10-15K, I feel better lol. my physical credit card is on the way. should i get a physical debit card too? is there any special perks for debit card payments? is it LTF? also are there any other benefits of slice cc apart from up to 3% monii??
