Galaxy 3 being ruling the market got a tough fight from the LG Optimus. Both phones being in the same price range and nearly same hardware specifications are making people confused to select anyone between them.
Comparing, both the phones have got almost similar hardware specifications so here are the differences,
Both the phones having touchscreens, LG Optimus has got TFT Resistive Touchscreen while the Galaxy 3 got TFT Capacitive Touchscreen, always capacitive is better than the resistive. LG Optimus has 256K Colors while the Galaxy 3 got 16M colors, the more the colors better will be the display and also some of the android apps require phone with 16M colors
Comparing the screen size LG got 3.0inch screen with 320 x 480 resolution while the Galaxy 3 got 3.2inch screen (bigger) with resolution of 240 x 400 (that's a really bad and odd resolution) due to this very few apps don't run on the Galaxy 3, it is good for daily use phone as even the movies run great.
In the hardware sense LG got 156MB RAM and 600MHz processor, while the Galaxy 3 got 256MB RAM and 667MHz processor. The 3G support of both the phones is good but the Optimus got 7.2 Mbps and the Galaxy 3 got 3.6 Mbps. Comparing WLAN (WiFi) Optimus supports WiFi G and WiFi B and Galaxy 3 supports WiFi B, WiFi G and also WiFi N which provides great speed. Regarding Bluetooth Optimus has got Bluetooth 2.1 while Galaxy 3 got Bluetooth 3.0
Comparing both, its clear that the Galaxy 3 is always good and way better than the LG Optimus. So we suggest you to go for it! :)
