What is on the market today is based on a product pipeline of 18 months ago. LG does have a "nice" looking phone in the G2 but it was just last year their LG Optimus G (G1) was neither sexy or awesome device beyond that it shared the Nexus underpinnings.
I have had several LG devices and when you compare LG to Samsung well Sammy has several leads over them. First lets talk about Samsungs new 3D memory technology that will be light years ahead of the competition and will be patented. Next battery, do you want a non-removable battery that once it starts to get recharged too many times begins to lose capacity (iphone too) or do you want to swap and go. Do you want to be limited to what you can carry on your phone with 32GB (before formatting, OS, and bloatware) or do you want the ability to carry pics, media, and other material on a microSD card.
Finally lets talk about updates, which in the US are controlled very tightly by the carrier (verizon being last to the party just about every time) yet LG does NOT have a proven track record of supporting their phones or putting out updates. Lets go back to the Optimus G (G1) it arrived with ICS, is stuck at 4.1.2 and will never see 4.2.2 or even 4.3. The G2 has 4.2.2 but will likely take 4-6 months to get 4.3 and likely will never see 5.0. Samsung has at least pushed out updates, the GN2 will likely get bumped to 4.3 instead of 4.2.2 since the GN3 is going to have 4.3 (rumored) at launch so it make sense to just update the GN2 shortly after with 4.3.
So while the hardware looks sexy, it is also like everything else in life. You can have a Ferrari but without the matching engine you really are just for show. Do a quick search on Chinese Ferrari's and the fake one's being made to look identical to the real one's. The difference IS beyond looks.
