Just ask them, do Su35 have equal system?
Nope, Russians are well behind in this with their cumbersome SAP-14 pod and derivatives (use older 80s-90s version of DRFM tech still, and are noisy as hell opening up adversary option for ECCM)
India for example found them quite deficient (for MKI) and went with local design for RWR and israelis for dedicated pod (ELTA El/M-8222...uses much newer+upgradable DRFM)

Right now going forward (as direct consequence of this), India is developing own ASPJ pod and DCMAWS pod....as russian one is just not improving/competitive in this field:

Thus it is safe to say top tier NATO one like EPAWSS, would be one of best....far surpassing Russian one.
Extreme Russia-fanboys (like x-treme fanboys in general) are often... how shall we say, not very factually+logically-inclined.
As others mention though, it is unlikely EPAWSS will be available to Indonesian F-15 EX.
But indonesia can get some very good EPJ, MAWS etc anyway, they would have to scope and plan these things appropriately before they commit to something this year.
