If the prices are similar to Germany, you’ll also have good discounts and reduced prices for the Phone (2), so it becomes a more attractive option in terms of price.
However my above listing still stands, if you want to go “all-in” with most features and best performance, the (2) is the way to go. One thing to remember though: That Phone started with Android 13 and is said to get three major Android updates, it already got 14, will get 15 and in theory Android 16 would be the last upgrade. Also four years of security updates would end sometime in mid 2027.
The (2a) will also get three major Android updates, vut already started with Android 14, which means it should get Android 17 as the last big update, it should receive security updates until early 2028. Software aside the (2a) is IMHO best price-performance package if you want the full Nothing experience, so the thoughtful transparent design and glyph interface.
