Which itr form should i use - itr4 or itr2?

Last 2 years I have been submitting ITR4 due to some income from consulting I had done (got income under sec 194J). In FY 2016-17, I did not get any income from consulting (no income under sec 194J). I had income only from bank interest and capital gains on sale of mutual fund units. Now, for AY 2017-18, which ITR form must I use? If as a continuation I use ITR4 (now ITR3), I will have to show zero income under business section. Can I use ITR2? Or is it advisable to use ITR4 (ITR3)?
