Tuttle is a lot more colloquial / modern, yes. About 13,000 examples in all, so more than ABC C-E but fewer than PLC. If you just want a ton of example sentences you could also look at the larger Oxford dictionary (tough to count examples in that since they're lumped in with derivatives but probably something in the range of 80,o00), though its examples don't have Pinyin, and quite a few of them are in the same formal / written / etc category as examples in PLC.
You can see quite a lot of example sentences in the demo versions of our dictionaries, so I'd recommend checking those out - if you download the demo of a dictionary in "Add-ons" you can browse sample entries from it. (just go into its Add-ons page after downloading it and you'll see a "Browse" button)
It's kind of a delicate balancing act with PLC, we want it to be good enough to be useful to people but not so good that it eliminates any benefit to buying an add-on dictionary (since we still need to make money).
