Comparing FIITJEE and IITian Guide is a bit challenging as they serve purposes and have different approaches.

FIITJEE : it is a well known coaching institute in India that primarily focuses on preparing students for competitive exams, including JEE.  It provides comprehensive coaching, study materials, test series, and guidance to help students excel in these exams. It has proven track record of producing successful students who secure admission to prestigious institutions like IITs.

IITian Guide : on the other hand it seems to be a platform or Guide specifically tailored for IIT Aspirants. It might provide resources, tips and guidance to students aiming for admission to IITs. However it's essential to note that without specific details about the nature and quality of resources affected by IITian Guide,  it's challenging to assess its effectiveness compared to established coaching institutes like FIITJEE.
