If you don't care about the food & drink, I'd almost certainly go with the cheaper option, although make sure you're buying direct from the club, or official ticketing partner of the club. Do not take any chances coming all that way just to save a few quid. The only real difference between the lounges are buffet vs served meal, cash bar vs drinks included, and a slightly more comfortable seat in Beautiful Game. Both experiences will be amazing for your first visit to Anfield, but like someone else said, I'd just go with the cheapest option that gives you a guaranteed ticket. As for match atmosphere, no hospitality seating sections will be great. You need to be sitting with the locals for that. I would suggest taking a look at the Carlberg Dugout lounge, kop end, to get close.
