Is lemon juice in a bottle the same as squeezing a lemon?

Could you elaborate on the differences, if any, between lemon juice that comes in a bottle and lemon juice that is freshly squeezed from a lemon? Are there any nutritional differences, or does the taste and aroma vary significantly? Are there any additives or preservatives in the bottled version that might impact its overall quality? Ultimately, is one form of lemon juice objectively better than the other, or does it simply come down to personal preference?
