I´ve burned not many media with the GH24NSD1, but it should be similar to the 24NSB0/C0.
I don´t have a 224BB, but newer Samsungs like DB and GB are similar to the LG. My RITEKF1 and RITEKG05 works better in the LG, MBI 01RG40 better in Samsung.
With MCC-media theres not much difference, an annoyance with LG are the limited write speeds for 16x-media. Only 8x and 16x, no 12x.
Both are very good DL-writers.
So I say it makes only sense to buy an LG if you want a new writer. The LG is here very cheap, ca. 11€ without shipping.
I scan full speed because I say a good burned media should look good with 16x scanning speed. But most ppl here scan 8x because they began with older writers which had general problems with high scan/read-speeds, I´ve noticed this with my older Liteons, even with the x24 B. My 124 F works better at highest speed, but older DVDs like 1x-4x-media from PRINCO, Optodisc,Interaxia and some of my TY-fakes can´t be read at max. speed, the 124 mostly refuses to scan those media faster than 8x. If I try to scan above 8x it only scan 6x-CAV
So I would say stay 8x with your Lite, because it don´t like highest speed and the other ppl with B/C-series also use 8x
