Dear Ashish
Both MP Vijay Kumar(For Brevity Call MPV) Sir Book & DS Rawat(For Brevity Call DSR) Sir Book Are One Of The Best Books & You Should Choose The One Among Both Of Them Keeping In Mind Following:-
Both MPV Sir Book & DSR Sir is Recommended By ICAI.
MPV Sir Book Is A Devil Of 1030 Pages in Comparison To DSR which Contains 718 Pages.Here U Should Check The Time Factor & Your Retention Power.
MPV Sir Book Contains More Therotical & Practical Problems Than DSR.
In MPV Sir Book IAS/IFRS Are Given Along With The Relevant AS While In DSR Seprate Chapter For IFRS Is There. However Significant Differences B/W IndAS/IAS/IFRS is Given At The End Of Each AS(Which Is Very Important).
My Opinion
In My Opinion First Of All You Should Check ICAI MODULE For FINANCIAL REPORTING(Volume 1 only).
It Contains All The AS's In About 250 Pages Along With Problems.For Solving Furthur More Problems You May Refer PRACTICE MANUAL (i.e Vol. 3). It Would Be More Than Enough In Less Time From Exam Point Of View Only.(Best Option)
However If You Want To Go Otherwise U Should Refer MPV Sir Book Provided U Have Enough Time. If U R Lacking Time Then Without Any Second Thought Go For DSR Sir Book.
The Most Preferable Choice Of Majority CA Students is DSR Sir Book.
Don't Go For Dolphy D'souza(Which Is Also Good). It Is Better To Refer It After Qualifying CA.
