That depends on your investment objectives. You need to find a fund that suits you and not a fund that's doing well on a popularity scale. People invest in long term or short term, for dividend or growth, can take more risk or low. First define that you want. Even better, write down an investment goal.
Of your tax saver investments, I myself invest in SBI Magnum. Its rated well and has done better than almost all the others in its category both in short and long term. You could continue investing in that for 80c purposes. Another decent one in this category on your list is HDFC, also concentrates on large cap so you could continue to split your tax saving investments between these 2.
