If Lightroom had Apertures Auto Enhance (very best I've seen), White Balance (skin tone option), non-destructive workflow, color overlays when brushing, etc this would be a lot easier to swallow.
Lr's lens correction and water marking does help.
I guess it depends on what you moved from. A mac mini that was cursed with problems (crucial SSD and 16 GB ram) but had to reinstall Mavericks every two restarts. Before that it was a 2010 27" iMac with spinning HDD. My plugins are (NIK, Noiseware, etc.) are much improved and batch processing is awesome. Best feature is editing in Pixelmator for those special photos.
