Purifi 2 Way BS or SEAS KingRO4Y Mk III

Hi Friends being a newcomer in the wonderful world of DIY audio

I am eager to know what you gentelmen feel pros and cons between

Purifi 6.5" Woofer with Berrlilum Tweeter 2 way Bookshelf ( in this also confused what config with passive radiatpr or sealed or ported Purifi Passive too expensive no one has mentioned whats difference between purifi PR Vs other PR like Dayton or wavecore or SB acoustic

Other model that also is on my mind is SEAS KingRO4Y Mk III kit
Its a 3 way

I have Hypex nCore amps and miniDSP 2x4HD and Hypex DSP also since SEAS gives Hypex DSP configured file

cheers
