Which is better, Sass or Less? Explain

• Looping:- LESS allow the loops but that is only through the recursive calling and this can lead to a little tricky coding and maintaining this code will be a difficult job and SASS there are control derivative like @if, @for, @each and @while which are easier to use
• Cross Browser Support:- In SAAS, CSS transitions can be implemented by writing just one CSS rule and it adds up all the browsing rules for the coder.
• Mathematical Operations:-SASS performs more accurate mathematical operations than LESS
• Compilation Time:-Compilation time of SASS is less than LESS
• Documentation:-SASS documentation is easier to read and understand as compared to LESS

Above points clearly prove that the SASS is better CSS pre-processor than the LESS.
