SMS College is one of the best Rajasthan colleges and is definitely a better option than RUHS College. 

• Infrastructure: SMS has excellent infrastructural facilities and a beautiful campus that enhances the overall learning experience.
• Faculty: The faculty pool is diverse with highly dedicated and hardworking professors. They act as a true mentor in guiding students in every aspect of life whether it is academics or non-academics. 
• Pedagogy: The faculty adopt unique pedagogy to engrain the topic in the student's mind. 
• Fees: RUHS MBBS fees are INR 33,500/Yr while INR 3,140. The high difference in fees is enough of a factor to choose SMS over RHUS.

RUHS on the other hand is still in its development phase. From the outside, it may be lucrative but the situation inside is pathetic. Students are given very limited exposure and the focus on extracurriculars is also less. 

Other options you can consider are RNT, Udaipur, SPMC, and Bikaner, but if you want to experience college life at a new med college, then RUHS is the one for you.
