These two chips, the ICODE SLIX2 and the NTAG212 are from different NFC chip families. The ICODE SLIX2, manufactured by NXP belonging to the ICODE family, and the NTAG212, also manufactured by NXP.
The ICODE SLIX is part of NXP's ICODE family of chips. The ICODE series is older than NXP's NTAG series and has a number of significant differences - particularly a longer 8 byte UID and a longer memory retention specification of 50 years. However, this ICODE SLIX2 variant is newer and contains a large numebr of feature enhancements.
Generally, these chips are not commonly used in mobile phone NFC applications. While they are similar in cost to the NTAG series, Seritag generally recommend NTAG unless the additional specified memory retention lifespan is specifically required. The ICODE chips are not available in as many formats as the NTAG chips and are typically made to order.
The NTAG212 chip was launched in 2013 alongside the NTAG210, NTAG213, NTAG215 and NTAG216. The NTAG212 holds a similar amount of memory to the NTAG213 at 128 user bytes and while it has some more features than the original NTAG203 chip, it's not as full featured as the NTAG213, NTAG215 or NTAG216.
Seritag's recommendation on the NTAG212 : avoid.
Both these chips have a strong ScanStrength and will work very well with mobile phones.
