Yes, it's definitely taste. Arguably, 1, 2 had better story lines, but I preferred the open world exploration and vast amount of side quests in 3 and NV (and in the entire Elder Scrolls series) to the mostly linear nature of the first 3. Tactics was kind of meh any way you look at it. I'll just suffice it to say that to me, the entire series is a must have, from start to finish, and whatever may come along. Each game has it's strengths and weaknesses, but all are worth exploring.
