Radar: LCA mk1 currently has Elta-2032 radar which is superior than Klj-7 radar.
True, from manufacturer data available in public.
RCS: LCA's RCS is far lesser than JF-17
True, because of the small sice, less reflecting surfaces, use of RAM coatings and at last point, high use of composites materials.
EW suite: LCA has been integrated with indigenous designed EW
Not true, certain parts of the whole EW system are indigenous, like the RWR which are used in MKI or Mig 27 too. However, that doesn't related in any superiority. Infact, from what we know so far, JF 17 should have at least advantages in terms of EW sensors, since it already uses MAWS as part of the EW, while LCA doesn't so far.
Low wingloading and high dry TWR are good, AoA not bad yet, but will be improved before final FOC. No reliable data available for JF 17 in this field.
Besides the dvantages mentioned above, the airframe has also the advantage of a dedicated pod station, so no limitations of weaponstations during LGB strikes, or carrying other pods. Avionics are pretty comparable and propper 4th gen standard. One could only find advantages for each fighter in certain fields, Dash HMS and Litening LDPs for LCA, or better MDFs for JF 17, but overal they are equal here.
There are some points that you didn't mentioned:
Engine - advantage LCA, more power, more life, more cost-effective to operate, less maintenance
Weapon package: advantage for JF 17, more weapons integrated or on offer, while LCA only has LGBs and WVR missiles integrated yet. The only other weapon that is known to be added yet is Derby, so we have to wait and see.
Costs: lower unit cost of JF 17 on the one side, lower operational cost of LCA on the other (less airframe parts, less movable parts, more fuel efficient engine)
Both are light class, low end fighters and will be good additions to the air forces with their multi role capablities and without much dependence on foreign restrictions. LCA was developed with a higher standard in mind and the addition of foreign techs just increased this, which gives it advantages in in air combat, operational terms, or future potential.
JF 17 mainly benefits from it's low cost, the early induction into PAF and the maturity it now gets through operational service, just like the addition of more and more weapons to make it versatile especially in the strike role.
