The LP64 multiband adds quite a bit of latency, the Sonitus eq doesn't (or if it does I've never noticed it). Don't know about the vocal strip as I don't use it much if at all.
 
The LP64 is really more of a tool for use at the mastering stage than while tracking. Latency is much less of an issue at mastering. Other high latency introducing culprits include compressors/gates that look ahead, convolution reverbs (and guitar amp emulators that use convolution to emulate speaker cabs) and anything that needs to read the audio in advance to give it enough time to process it or things like through-zero flangers which cycle the effect ahead of the now-time as well as behind it, if that makes sense.
 
The usual work-round is to use a different plugin as a stand-in while tracking then switch that for the latency producing one at the mixing/mastering stage. Someties plugins come with a version intended for live/tracking use which can then be switched for the "normal version" once the audio is recorded (Waves REEL ADT is one example).

Lots and lots of folks find out the hard way that some plugins can really do a number on the latency during recording.
 
I certainly found that out before, as well, and it takes time and sometimes trial and error, to ferret out which plugins are not meant for use during tracking/recording.
 
Some web sites have published latency values for their various plugins, or it can be in the documentation that comes with a downloaded plugin.  Look ahead processing is a term that indicates that some latency will be required for a given effect to do its thing.  Other times, if the plugin doc/ad indicates it is a Mixing or Mastering plugin, it might be a clue that it will add latency.  Convoluted reverb plugins can add latency, as well.
 
(edited to add) If not sure about a plugin's contribution to latency, sometimes I will do a quick search on the web, using the plugin name and the word latency.  If that plugin does add a bunch of latency, there is a really good chance that someone has posted about it somewhere, and you can usually get a feel for that just from the snippets of content shown on the search results pages.
