@sottwell, I have only one instance of pdoMenu and have not spent much time with it, but I do have an error with it that instance I have not had time to fix. As for Wayfinder I have used a fair amount so I will list what I would say are the major differences.
1. Performance, see the iterateType Property, if PDO is set in a simple test it seems to take about half the time to load verses Wayfinder/getIterator. When set with PDO and used with the default Chunks, so not set via properties it is more than 4 times faster, 700ms vs 170ms. It seems to be marginally faster when set to getIterator which is the default. Note if you need columns/TVs processed then you will need to use the getIterator value. I did just a simple test with about 315 resource list generated.
2. Easier to set up and customize, in my opinion anyway. There are only two Chunks used, a chunkWrapper and an chunkItem. If you want to have different chunk(s) for different levels simple add a the level number that you wish to override, example for item level#2:
&chunkItem2=`myNavChunkItemLevel2`
I still have some work to do regarding generating classes and setting a placeholder in the Wrapper/Item for Active/ActiveParent as a bool. Also I just made another commit to fix the docs and a small bug and have not implemented all Wayfinder features, not sure I will.
Comparison Example:
MenuBuilder:
[[!menuBuilder?
&startId=`0`
&chunkItem=`mbItemTest`
&chunkWrapper=`mbWrapperTest`
&debug=`0`
&limit=`1000`
]]
// mbItemTest Chunk:
<li>
Count: [[+mbCount]] | Level: [[+mbLevel]] <a href="[[+mbUrl]]" class="[[+mbItemClasses]]">[[+mbTitle]]</a>
[[+mbChildren]]
</li>
// mbWrapper Chunk:
<ul class="[[+mbClasses]]">
Count: [[+mbCount]] | Level: [[+mbLevel]]
[[+mbChildren]]
</ul>
Wayfinder:
[[!wayfinder?
&startId=`0`
&rowTpl=`wfItemTest`
&outerTpl=`wfWrapperTest`
&debug=`0`
&limit=`1000`
]]
// wfItemTest Chunk:
<li[[+wf.id]][[+wf.classes]]>
Count: -- | Level: [[+wf.level]]
<a href="[[+wf.link]]" title="[[+wf.title]]" [[+wf.attributes]]>[[+wf.linktext]]</a>
[[+wf.wrapper]]
</li>
// wfWrapper Chunk:
<ul[[+wf.classes]]>
Count: -- | Level: --
[[+wf.wrapper]]
</ul>
