Rendering stems for another DAW (Mixbus) should I wait to use send effects?

[Metrobot]

I have a mix session in Reaper where all of the tracks are eq'd and balanced where I want them. I want to render render each track and send them through Mixbus. I haven't added any send effects ( Reverb, Delay..etc)
Should I wait to treat the tracks with send effects after I've imported them into Mixbus or should I treat the tracks in Reaper and render the effects returns as a separate tracks to be mixed in mixbuss?
