Default Poppet vs mpfi which is better?

So my 99 suburban is in need of a fuel injector replacement. Are there any benefits to switching to the multi port type setup vs the oe spider?

Also i apologize, I'm sure this topic has been covered before, just looking for some fresh insight. I've owned this truck for 4 years and it's been down for the last two, starting with head gasket issues. I just really want to get her back on the road. Plus i just traded my trailblazer for a 30ft camper and i need something to tow it.

Default My bad :(

Haha, yeah and I'm a noob on this forum. I searched and found a lot of spider related troubleshooting threads, but nothing on the benefits of conversion.
