I would label this as a personal preference.
All will grow beautiful plants if administered correctly.

This sounds like a loaded question.
Potential heated debate?

LOL....no debate @Maryland Guppy. I dose with PPS method, but was just wondering if the EI method was better. Also was curious as to which is more cost effective, which could help better control algae, etc. Things like that was the reason for the post.

I was under the impression that EI was for maximum plant growth and required more maintenance. PPS is designed for good plant growth with less maintenance. I'm using PPS and plants are growing well. I need to trim again and remove runner plants so my fish have some space to swim.

Actually, the one that fists your individual situation best would be the better choice. Guppy's reply is very correct

Since this is not a loaded question, I'll explain more.

My choice was PPS Classic.
Reason being I was initially skeptical of adding "chemicals" to my water.
Testing to determine needs put the minimum ferts in the water.
This did not eliminate weekly WC for me just reduced the amount that needed to be changed.
I almost have this down to a predictable science in a hi-tech 40 gallon.

I have been forced through water testing to learn about fertilization.
It has been a successful learning experience for me.

Less ferts would always be more cost effective.
Algae control would be dependent on not only ferts but each individual lighting and CO2 scenario.
I consider lighting and CO2 as two more fertilizers.
Aggressive behavior with any of these items can cause a severe imbalance = algae farm.

Ahhhh....that sounds great, @Argus! I am also using the PPS method and have started seeing increased plant growth. I really like the "less maintenance" part.

By dosing PPS-Classic I began testing daily for two weeks.
Trying to get a feel for fertilizer uptake by plants.
My tank has enough NO3 due to bioload.
WC's were based on rising NO3.
By measuring I found PO4 to be near zero.
As increased dosing of PO4 occurred more NO3 was consumed.
To a point now where I need to dose NO3.
I never tried to measure K and kits for such are notably unreliable.

Measuring Ca and calculating the Mg content also helped.
Plenty of Calcium but plants were sucking up all Mg.
Needed to prepare this and begin dosing, now @ 5ppm.

I have also done much LED experimenting.
Recently traded 6-UV385nm 3 watt LED's with 6-Full Spectrum 3 watt LED's.
The full spectrum channel although dimmed and color not as appealing has promoted much more growth.

Are those ferts included in the PPS packages that are available to buy? I surely hope so

I do EI with an auto doser, i do a 1/3 recommended doses every 2 days, and auto dose excel every day. I have a python water changer so it makes it easy as i just hook it up to a sink and go. doing a 50% water change each week insures that my fish is living happily, i just do it every saturday. I can see if i had a much larger tank changing 75g each week would be terrible. In a few years i may do pps because ill have to upgrade to a 120 or more.
