I honestly wouldn't expect a perfect guitar for that price from a big manufacturer. After working in a music store for about a year, I've come to see quite a few ugly flaws. Gibson? Since playing Custom Shop versions, I've yet to play any Gibson USA worth buying. The USA models have larger frets. Gibson will tell you this is for easier playing, but it isn't; it's so if they screw up the neck, they can simply grind their mistake out with the PLEK machine until it's level (though I question the conditions under which this is done; I tried to like a LP Jr. a month ago and it was great until the fret buzzing revealed itself during its first setup). The wood they use is also sub-standard; play a good piece of mahogany and you'll quickly realize the choked tone most USA Les Pauls possess. And while many of these guitars will age well, they just can't compare to the Custom Shop equivalent.
Fender? Fender makes a more consistent guitar than Gibson. They're not made by hand, and so the necks are more consistent from one guitar to the next. The bolt on necks are easier to deal with and honestly, probably better for resonance than Gibson's method (look up how the Gibson USA models are attached; short neck tenons stifle tone, unlike the Custom Shop's historically accurate and far superior long tenon). The problem? Plastic finishes and sub-standard wood muffle tone. Wood doesn't age properly and the fretboard becomes uneven. The Custom Shop models, on the other hand, are incredible. I recently got a NOS '56 RI Strat, and it's perfect in every way (even has a lacquer finish!).
ESP? Seems hit or miss. I've played some excellent guitars by ESP, and some terrible ones. They seem similar to Fender in that nothing is done by hand. My guess - both with ESP and Fender - is that the guitars leave the factory in great shape, but because of manufacturing techniques, by the time they reach customers, have shifted and changed so that most QC at the factory was a waste.
For 1600 EUR, I'd look at the used market. I truly believe - and I've played a LOT of guitars - Fender and Gibson Custom Shops are the best made guitars money can buy.
